My intrusive thoughts are getting to me. Advice welcome

I don't like them. They are particularly troubling. I don't think I'll act on them but they're persistent and pervasive. I am trying to meditate and other things. I think anxiety is causing them fear is making them worse. Such an uneasy feeling. I try not to think them and that creates more. This is becoming a thought loop I can't seem to shake. All advice welcome
