Definitely sounds like you're worn out and depressed. Please don't let your one experience with meds prevent you from getting professional help. You may have been on the wrong meds or the wrong dosage. Perhaps you also need talk therapy.
One thing that might help is if you stop arguing with ds/ the dad. Let him live his life as he chooses, whether you agree or not. He's not a teen anymore, you and dh no longer have to raise him. If he tells you things that bother you, just change the subject. Fewer arguments might lighten your load.
Should the Judge in the teenagers rape case be struck off ?
What did you you think you would have by your current age that you don't?
