I found out that one of my very good friends from back in north carolina killed himself yesterday. I am in complete shock. I don't know how to feel. His girlfriend, also my friend broke up with him, and the next day he shot himself. He had a long struggle with mental illness, and because of lack of health insurance and money, he got no treatment. His gf called me yesterday to tell me, and she cried for three hours on the phone with me. I didn't know what to say or do to make her feel better. I feel bad that i left them and moved to texas. Maybe if i had stayed, i could have helped him. I'm worried that she will try to do something. I upset that I can't even make it back for the funeral. He was only twenty. He was so young. I have flashbacks of the last time I saw him. How could this happen, i have so many emotions, guilt, anger, sadness, confusion, etc. How do I cope with this?
