Is it ok to give yourself reassurance not in the sense of “don’t worry you’re not a p, it’s just your mind tricking you” but in the sense of “you’re gonna get better, you’re gonna be happy again soon”

When I reassure myself that I no I would never do that, I don’t believe it & when I’ve been using the same reassurance for a while it doesn’t work the same way as it use to?

I’ve heard it’s not good to seek reassurance or give it because it lowers your tolerance to uncertainty. But how do I avoid seeking reassurance when my thoughts and doubts are so bad, I genuinely just don’t know anymore if I’m a bad person or if it’s just OCD? I know I’m supposed to sit with the uncertainty, but how can I do that when the uncertainty has me unable to trust my own brain? Especially when the OCD is real event and POCD? How can I not seek reassurance when I feel so alone and so abnormal and just don’t wanna feel that way anymore? In turn, I see so many people on here struggling so bad and my heart breaks for them. How can I give advice to towers without giving them reassurance and hurting them in the long run?

I see a lot of posts and comments here along the lines of... "the thoughts/urges aren't you -- they're just OCD." Though this is often true and comforting, isn't this just a form of reassurance? The way to beat OCD is by accepting that the distressing thoughts MAY be true/real, a.k.a. "from you" or "not just OCD." By brushing distressing things off as "just OCD," you excuse the thoughts and therefore feel reassured. Obviously it is good to be aware of what OCD does to you and know when you're experiencing a spiral, but crediting all distressing thoughts to OCD is a way of finding certainty about them. What do you guys think of this? Am I right or wrong? This is just the way I think about it, but I see the "this is just OCD" thing so much on here and I often wonder if that is a form of reassurance.
