I will share my sorrows and experiences losing my sister (when I was a young child), losing my late husband and losing my young daughter.
Here are some clips from Wikipedia ... https://en.wikipedia.org/wiki/Grief explaining some types of grief due to certain losses.... these apply to me.
Death of a sibling
The loss of a sibling can be a devastating life event. Despite this, sibling grief is often the most disenfranchised or overlooked of the four main forms of grief, especially with regard to adult siblings. However, the sibling relationship tends to be the longest significant relationship of the lifespan and siblings who have been part of each other’s lives since birth, such as twins, help form and sustain each other’s identities; with the death of one sibling comes the loss of that part of the survivor’s identity because “your identity is based on having them there.”
The sibling relationship is a unique one, as they share a special bond and a common history from birth, have a certain role and place in the family, often complement each other, and share genetic traits. Siblings who enjoy a close relationship participate in each other’s daily lives and special events, confide in each other, share joys, spend leisure time together (whether they are children or adults), and have a relationship that not only exists in the present but often looks toward a future together (even into retirement). Surviving siblings lose this “companionship and a future” with their deceased siblings.
Siblings who play a major part in each other’s lives are essential to each other. Adult siblings eventually expect the loss of aging parents, the only other people who have been an integral part of their lives since birth, but they do not expect to lose their siblings early; as a result, when a sibling dies, the surviving sibling may experience a longer period of shock and disbelief.
Overall, with the loss of a sibling, a substantial part of the surviving sibling’s past, present, and future is also lost. If siblings were not on good terms or close with each other, then intense feelings of guilt may ensue on the part of the surviving sibling (guilt may also ensue for having survived, not being able to prevent the death, having argued with their sibling, etc.)
Death of a spouse
The Death of a spouse is usually a particularly powerful loss. A spouse often becomes part of the other in a unique way: many widows and widowers describe losing ‘half’ of themselves. The days, months and years after the loss of a spouse will never be the same and learning to live without them may be harder than one would expect. The grief experience is unique to each person. Sharing and building a life with another human being, then learning to live singularly, can be an adjustment that is more complex than a person could ever expect.
After a long marriage, at older ages, the elderly may find it a very difficult assimilation to begin anew; but at younger ages as well, a marriage relationship was often a profound one for the survivor.
A factor is the manner in which the spouse died. The survivor of a spouse who died of an illness has a different experience of such loss than a survivor of a spouse who died by an act of violence. The grief, in all events, however, can always be of the most profound sort to the widow and the widower. Emotional unsteadiness, bouts of crying, helplessness and hopelessness are just a small sample of what a widow or widower can expect to face. Depression and loneliness are very common. Feeling bitter and resentful are normal feelings for the spouse who is “left behind”. Oftentimes, the widow/widower may feel it necessary to seek professional help in dealing with their new life.
Furthermore, most couples have a division of ‘tasks’ or ‘labor’, e.g., the husband mows the yard, the wife pays the bills, etc. which, in addition to dealing with great grief and life changes, means added responsibilities for the bereaved. Immediately after the death of a spouse, there are tasks that must be completed. Planning and financing a funeral can be very difficult if pre-planning was not completed. Changes in insurance, bank accounts, claiming of life insurance, securing childcare are just some of the issues that can be intimidating to someone who is grieving. Social isolation may also become imminent, as many groups composed of couples find it difficult to adjust to the new identity of the bereaved, and the bereaved themselves have great challenges in reconnecting with others. Widows of many cultures, for instance, wear black for the rest of their lives to signify the loss of their spouse and their grief. Only in more recent decades has this tradition been reduced to a period of two years, while some religions such as Christian Orthodox many widows will still continue to wear black for the remainder of their lives.
Death of a child
“It is a fearful thing to love
What Death can touch.”
Josephine Jacobson, The Instant of Knowing (Library of Congress, 1974), 7.
Death of a child can take the form of a loss in infancy such as miscarriage or stillbirth or neonatal death, SIDS, or the death of an older child. In most cases, parents find the grief almost unbearably devastating, and it tends to hold greater risk factors than any other loss. This loss also bears a lifelong process: one does not get ‘over’ the death but instead must assimilate and live with it.
Intervention and comforting support can make all the difference to the survival of a parent in this type of grief but the risk factors are great and may include family breakup or suicide.
Feelings of guilt, whether legitimate or not, are pervasive, and the dependent nature of the relationship disposes parents to a variety of problems as they seek to cope with this great loss. Parents who suffer miscarriage or a regretful or coerced abortion may experience resentment towards others who experience successful pregnancies.
Loss during childhood
When a parent or caregiver dies or leaves, children may have symptoms of psychopathology, but they are less severe than in children with major depression. The loss of a parent, grandparent or sibling can be very troubling in childhood, but even in childhood there are age differences in relation to the loss. A very young child, under one or two, may be found to have no reaction if a carer dies, but other children may be affected by the loss.
At a time when trust and dependency are formed, a break even of no more than separation can cause problems in well-being; this is especially true if the loss is around critical periods such as 8–12 months, when attachment and separation are at their height information, and even a brief separation from a parent or other person who cares for the child can cause distress.
Even as a child grows older, death is still difficult to fathom and this affects how a child responds. For example, younger children see death more as a separation, and may believe death is curable or temporary. Reactions can manifest themselves in “acting out” behaviors: a return to earlier behaviors such as sucking thumbs, clinging to a toy or angry behavior; though they do not have the maturity to mourn as an adult, they feel the same intensity. As children enter pre-teen and teen years, there is a more mature understanding.
Adolescents may respond by delinquency, or oppositely become “over-achievers”: repetitive actions are not uncommon such as washing a car repeatedly or taking up repetitive tasks such as sewing, computer games, etc. It is an effort to stay above the grief. Childhood loss as mentioned before can predispose a child not only to physical illness but to emotional problems and an increased risk for suicide, especially in the adolescent period.
Children can experience grief as a result of losses due to causes other than death. For example, children who have been physically, psychologically and/or sexually abused often grieve over the damage to, or loss of, their ability to trust. Since such children usually have no support or acknowledgement from any source outside the family unit, this is likely to be experienced as disenfranchised grief.
Relocations can cause children significant grief, particularly if they are combined with other difficult circumstances, such as neglectful and/or abusive parental behaviors, other significant losses, etc.
