In my experience there is no Overcoming OCD. You live with it, you deal with it every day. Part of dealing with it is in recognizing the pain is going to be there no matter what, so would you rather spend a bunch of effort thrashing against the cage and still feeling that way or living your life and feeling that way. Some days, or nights especially, it's bad. But I'd rather get somewhere in life while I'm at it you know?
I feel like there's a lot of echo chamber mentality going on with all the rosie thinking and toxic positivity. It's ok to feel bad every now and then. But there's real power in looking at your OCD square in the eyes and telling it to f*** off. You're not ignoring it, you're not pretending the thoughts don't bother you, you're recognizing that they are YOUR thoughts and you get to decide whether they mean anything or not.
