It's in the title really, how do I stop thinking about things that are considered delusions? I just can't get it out of my head and I've tried to question the research that I believe is being done on me but I get scared and feel like the people who have access to my thoughts will laugh at my stupidity. I keep getting racing thoughts about it the situation I'm in at night which prevents me from getting off to sleep and it makes my heart pound during the day. I just don't know how to get rid of this. People think I'm delusional but I can't help thinking about these things, any advice?
