I'm just starting to read about PTSD because my brother has let me know he has it. He has been in a toxic relationship for about 25 years. We were very close at one time but are not now due to him pushing me away. He is very angry. I live far away and only text and email. He hardly ever writes back. He usually never returns calls. He started to open up to my mom / his mother that lives with me, now he has shut down. I am concerned about him as the last time we communicated with him he said that after his oldest child leaves the home he was done and completed his job here on earth and spoke of suicide. He still is working and did speak about wanting to see a therapist. I have given him many numbers and offered to prepay for his therapy but no response. I write everyday to him telling him I love him and that it will get better with therapy. I don't know what to do. I keep writing but don't know what else to do. Please help me. What can I do?
