Crazy? I highly doubt it, although it may feel that way at times. I completely understand the intrusive thoughts because I used to get them all the time.

My suggestion would be to try to keep your mind as busy as possible right now. Do anything that requires complex thinking on anything but those intrusive thoughts. When they enter your mind again, refocus on what you were working on and keep going. Each time you get another intrusive thought, refocus on what you were doing in the moment, not on the intrusive thought again. It may get very tiresome, but it's worth it. You may even train your brain to refocus automatically in the future.

Hang in there. We are all here for you.
