Oh please don't blame yourself Gina. People who kill themselves are often dealing with depression that ONLY a trained theripist can help them with. Their mindset is not rational, nothing that you or anyone else does helps. I have a family member who suffers from depression, she needs to be on meds the rest of her life, she has a chemical imbalance that causes depression. No one in the family could help her, only the pros and the meds do. When a person has these feelings they don't or can't think of anyone else, their confusion and pain are that great. Know that your friendship was important to her but that you are NOT or ever will be to blame. For anyone out there suffering from depression, please seek help. Don't suffer in silence, therapy and meds can and will make your life worthwhile again. Hugs to you Gina.
