Last Friday my brother hung himself in my mother's basement, the day before his birthday. We have known that he has been suffering from severe depression for a long time but did not know it had reached this point. Luckily my mother came home from work, saw the basement light on and went down. He had been there for maybe 10 minutes, not sure, but he was still alive. He was immediately rushed to the hospital and after a few days of agonizing uncertainty as to whether or not he would ever regain consciousness or brain function he has finally woken up. He has a breathing tube in so he is unable to talk and is heavily sedated, but he can respond to a question with a slow head shake or nod. I can't explain the feeling we all have now that he has regained consciousness and at how lucky we are that my mother found him when she did, as had only a couple more minutes gone by he would no longer be here, but I feel we may be getting lost in how happy we are that he is alive and may not be considering the fact that he may be in the worst hell imaginable right now. This was not a cry for help, this was it, he had made the decision to leave the world. And we brought him back. Now he is tied to a bed, unable to move or talk. I don't know if he feels differently now and is happy that he survived or if he is spending every waking moment in pain wishing he was not here, but unable to do anything about it. Not sure how long before they take him off of the breathing machine so he is able to talk to us, but apart from explaining how much we all love him, what can I say to convince him that life is worth living? I don't want to say the wrong thing, because he obviously felt/feels differently, and saying something like "life is a beautiful thing, etc" may make him feel worse. Any advice?
