therapy can be really triggering. I think it's a good idea to stop for a while if you can. But only if that would help u not think about it. If its really on your mind it may be better to push through. You are not pathetic. But it's normal to feel like it when you are depressed - don't believe the lies your depression tells you.
Hope the med change helps and you get some relief soon. Keep posting to let us know how you are going.
