Intrusive feelings

Sometimes I get these intrusive feelings of liking my thoughts, I hate the thoughts and I don’t want them and that “feeling” makes me so anxious and worried. It’s happened once but I worry that it’s happened more because I think “did I get that feeling” but now I’m worried that what it that feeling keeps happening over and over and I become my thoughts and all the guilt from that. I already have guilt enough and I’m just scared of these things happening again
