I just read a post to the doctor (that I can't respond to) about a girl that seems to be having delusions that people are plotting against her and that it could be linked to her Birth Control pill. Is this possible? I've been on the pill for years now and have never had this problem till recently. All of a sudden I've been suspecting that my fiance is cheating on me. There's really no reason why I should think this, but I've even gone as far as searching his laptop for proof (checking his history, searching files and pictures). I finally broke down and told him the other night and I was crying like crazy. I felt guilty for thinking these things, but I just can't seem to help it. I'm thinking of going to counselling, but could it be caused by the birth control pills? My doctor is thinking of taking me off it because she thinks it could be leading to my high blood pressure. Now I'm going to talk to her about this. It's scary.
