7.5 months in, feel like giving up

Thought I was strong mentally but this has taken me to new places. I go through periods where I think I’m doing better; then symptoms come back that I haven’t seen in a month or two, and I assume I’ve done something wrong and I’m losing all progress but I am pacing strictly. For people that have improved, did you experience this? Don’t want to give up but when I have nothing positive to work with it’s hard.
