Hi Nansue,
I'm happy you posted. I know it's hard when your kids suffer depression
My son is 21 and has had battles with this, but he doesn't always stick to taking the meds. I think he just doesn't feel like making it to the doctor's appts to stay on them, because he's had a lot of other stuff going on.
Could this be the case with yours? Maybe they don't like the side effects? In this case, the doctor(s) could try something new, maybe space out the appts a bit. Are they in counseling?
Well, I hope that YOU are hanging in there alright! Why don't you pick a day each week called Mom's day, get out, and do something for yourself to unwind. Please keep us posted.

Wishig you all the best!!
