I'm sorry it's hard right now - I've been there.
Is there any way you can get him on an injection?
We're still getting my son's at the right dosage, but I can't tell you how much better things got here when there was no longer a daily fight about meds.
If not, since I remember he's on SSI, which I guess means Medicaid too, can you see if your county has an Intensive Community Treatment (ICT) team? If they do, and you can get him in the program, they could come daily and handle his meds so you don't have to do it.
My son's shot gave out on him early & we've been supplementing with pills for a whopping 4 days and already I got the "all you want to do is feed me pills and change me into someone else" lecture. He gets another shot tomorrow, but I think we should continue the oral pills with it for awhile - I know a few more days & we'll be fighting like cats & dogs about it.
Actually worse than cats & dogs - I have 2 cats & 2 dogs & they almost never fight.
It does get exhausting though. I have lots of days where I dread getting up every morning - and if I go out, I dread coming home. Don't forget to take care of yourself too.
