Thank you one and all for your comforting but forthright words.
He has in the past been on medication for depression and I mentioned it to him last night. He is aware he has many issues that need to be addressed to get him back on the right path. I also, before I even posted, know that everybody is different and has different outcomes based on all so many variables. I did get the gist of what everyone's post to my message has conveyed. I am currently trying to also take care of myself so that I can further support him emotionally as the need arises. I am so very grateful for all that has been suggested and stated.
