Is it ok to give your mum a cuddle when your really low and upset it not reassurance seeking ? As have so many thoughts in my head that won’t budge

What did I do if I really want reassurance

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?

Sorry for getting on everyone's nerves by reassurance seeking. I am just struggling and feel like a real P. I just want some help while I wait on my next therapy appointment
