I can't do this anymore

As the wife of a man recently diagnosed with ADD, I want to know when do I get to stop being him mother?  When do I get to stop having to clean up behind him?  When do I get to stop being the only mature, responsible person in my home?  When do I get to stop hurting, crying loosing sleep?  Is it wrong to feel that everything is all about him, while I'm the one suffering?

I've lost my companion, my lover, my safe place to be to this invisible thing that isn't even new.  I've lost myself, the strong independent woman I once was, to a man who I love so much it hurt.  I feel like I'm walking on eggshells all the time.  I'm not sleeping very much and for the last few days, I cry because of anything, everything and nothing.  I don't feel like I'm living, and just barely surviving.  It's like I'm on life support, but I can't pull the plug.  I need the pain to stop.  I want to go to sleep and not wake up until he has himself under control.
