Six months of therapy and feeling demotivated

I’ve been doing therapy for six months (erp, act, then back to erp) and I’ve had a few periods of up to a week of feeling improvement — always followed by crashing lows. I just had three days of almost feeling normal (resisting compulsions effectively) followed by the lowest week of the whole six months (compulsions constantly).

I feel demotivated, like no matter how I try, I always go back to feeling overwhelmed. I find myself in this period not even interested in using my tools because the outcome seems inevitable.

I really want to be motivated and optimistic, though. Is there any advice you have for someone who feels tired in this way? thank you
