hard to tell if love is there

I’m 16f, and I have a partner who I do love but recently my ocd has been so bad. pocd and rocd both and they’re going hand in hand in destroying my relationship. my boyfriend (15) showed me old art he made of himself and stuff and it made my pocd trigger and now it won’t leave and I also feel like a cheater too with my rocd so now all I feel is anxiety in my relationship and I just want to know how to fix this and feel love again. any advice?
