Why is it wrong for someone with OCD to seek reassurance? Does it really prevent us from learning how to tolerate stress?

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'm trying to not seek reassurance today. I'm not going to. I'm not going to. I'm NOT going to!! Ugh. Why OCD why?

The subject of OCD matters to the sufferer because it feels like confirmation that they are fundamentally unlovable and unwanted—as if even existence itself doesn’t want them. They feel like an error, carrying a deep sense of guilt and shame, as if they were inherently wrong. They suffer from low self-esteem and a deep internalized shame, because long ago, they were fragmented and learned a pattern of fundamental distrust—especially self-distrust. But the real trouble doesn’t come from the content of the most vile or taboo thoughts. It comes from the fact that the sufferer lacks self-love. That’s why, when you begin to walk the road to recovery, you’re taught unconditional self-acceptance—because that’s what all sufferers of OCD have in common: if you aren’t 100% sure, if there isn’t absolute certainty, the doubt will continue to attack you and your core values. It will make you doubt everything—even your own aversion to the thoughts. You have to relearn how to trust yourself—not because you accept that you might become a murderer someday—but because you enter a deep state of acceptance about who you truly are. It’s not about becoming a monster at all. It’s about making peace with what lies at the root of the fear. Making peace with the guilt. With the shame. Making peace with yourself and the person you fear you might be. Because that fear is not rooted in reality. It’s not rooted in any true desire to act. It’s rooted in your identity—specifically, in what might threaten it. That’s what confirms the belief that you are fundamentally wrong. And OCD fuels that belief by using intrusive taboo thoughts to attack your very sense of self. But then I wonder: let’s say, for example, someone fears being or becoming a sexually dangerous person—how could that person practice unconditional self-acceptance? I would never accept myself if I were to harm anyone—the thought alone makes me want to cry. I know it’s not about whether or not someone acts on the thought. It’s about the core fear underneath it. So how do you accept yourself when the thoughts—and the feelings around them—feel so completely unacceptable ?
