Like imposter syndrome?

What do you do when you have a thought and you’re not sure if it’s intrusive or not? I just had one that was so strange and bad, and I can’t believe I just had it, but I’m almost afraid it’s not intrusive and there really is something wrong with me. I hate this.

His so I have a question. Should I feel guilty for things I do like without thinking or naturally. Like for example if I’m around a person I find attractive I will naturally try to be funny or come off as attractive not in a bad way like it just happens I’m not usually aware of it until after it happens.Sometimes I do and say things without an intention it just kinda happens and then My brain after it will Be like oh you did that because of this and that. Or sometimes it’ll tell me I did it for a certain intention that I didn’t do it for, but it’s hard sometimes when I do things without a certain intention so then I can’t tell my intentions and I spiral but sometimes my brain is right and it makes me feel guilty because if I knew that’s was my intention I never would have done it if that makes sense. Is this part of OCD

Does anyone else experience this lingering fear and anxiety because they think they’re capable of hurting someone? It’s killing me. I feel like I’m such a danger. I feel like I’m a predator. I feel like this awful person and I can’t shake it. I want to carry on with my day but I can’t. I don’t feel like I deserve it. I feel like I’ve done awful things. I can’t stop crying.
