It does sound like you're depressed, it also sounds like if you could take an anti-depressant the doc could tweak that. I don't think it's a side effect, I think it's breaking through. But unfortunately you're going to have to find other ways to deal with the depression than meds.
Do you see a therapist? That would be my first stop.
Next, you need to make an unbreakable routine of getting out of the house everyday. Like going for a walk or to a cafe.
