DBH, I can only echo what others have said, that I am so very sorry for your loss. You are absolutely not to blame. I think one thing all of us here have learned or are learning, is that we are all responsible for our own path in life, including how we choose to walk that path, whether it be through therapy, support groups, medication or choosing to do nothing. We cannot fix others, only ourselves. I agree with some of the other posters that you may find more understanding than you think in a suicide survivors support group, and I hope you'll at least give it a try. You, your sister and your loved ones are in my thoughts and prayers. (((HUGS)))
