How do you find happiness while dealing with OCD?

Lately I have been trying to do things that are supposed to make me happy, but my OCD makes me postpone them until I 'fix' the OCD or get reassurance. It’s as if my brain won’t let me feel joy unless I’ve somehow earned it by addressing all the intrusive thoughts and anxiety first. Even when I try to do something fun, the intrusive thoughts always manage to ruin it.It’s like I’m stuck in this loop where I can’t even relax properly because I’m so focused on 'fixing' myself first.? How do you let go of that mental block and allow yourself to enjoy life despite the OCD?
