Hi Brother
I too am very sorry for your loss. She was suffering, but she was still your sister and it's very sad you lost her in such a tragic manner.
How are your mother, her husband and children coping with this loss?
Wondering if you could have done more is something expressed by other members as well who've sadly also had the experience of losing a family-member this way. We have a resource here that might help you as you mourn and try to process the loss of your sister:
Recovering from suicide lossHere's an excerpt:
Losing someone that you loved or cared for to suicide is the absolute worse loss that anyone can endure. No is prepared for it and only those who have experienced it can know what it involves and how it feels.
This handbook provides some basic information for those who are bereaved by a suicide. It is based on the self-help philosophy of Survivors of Suicide (SOS). It covers topics frequently discussed at SOS support group meetings and concepts from the suicide loss literature.

This booklet is not a substitute for the mutual self-help offered through SOS or other support groups. It is a supplement to such support. It may be a resource for those in settings or communities without such services.

Recovery is not “healing” or “getting over it” or “closure.” Those terms do not apply to what you have experienced. Suicide loss does not go away and it can not be left behind.
You have not only lost someone dear to you; you have lost a part of yourself. You have lost your normality. You can’t get back your loved one or your friend... .

You can’t get back to who you were before your loss. A suicide, to some degree, changes those that it affects. However, you can get to a different normal, a “new normal.” You will always feel your loss, but you can move beyond its abnormal consequences.
Take care as you mourn your sister
