Dear KimmyDawn,
I'm very sorry to read about your brother.
I take it that when he phones you and says that then he's about to take himself to the hospital? It's really a good thing that he's willing to call you and let you know how badly he's feeling despite how sad his situation is right now... it shows and tells you that he really doesn't want to feel so badly. Not that anyone does want to feel that way, it's just very difficult for some people to actually tell someone else and to ask for help.
I hope you've heard from him since you wrote your first post and that he's gone for help and you know where he is now. Shocking worry for you all there, KD.
Thinking of you and your brother and your family.
I hope that a plan has been put into place and that he's gone to the hospital for help.
