I, like many others on this forum, have an irrational fear of contracting HIV. I came of age in the 1980's and early '90's when all the scare campaigns were going on and the media was in overdrive regarding the disease. My mother also had an irrational fear of it. I currently have no risk factors for this disease, yet there always seems to be a scenario where I could have contracted it. My sister (a clinical psychologist) says it is OCD. She recommended CBT. I have been through 2 rounds with only minimal success. I have so much trouble with the ruminating part. I can't seem to turn the switch off and just stop thinking about possible exposures. The latest one involved me convincing myself I sat on an HIV needle in the waiting area at the vet's office. I never saw a needle, never felt a prick, just an uncomfortable sensation when I got up from the bench. The benches are very hard, and I put more weight into my left leg to get up. The cartilage (not sure of correct anatomy here)behind my knee dug into the bench. It wasn't until an hour or so later that I really started to worry--all the what ifs. I went back to my CBT worksheets and tried to work the whole thing out, asking what is the evidence for and against, etc. My mind won't let it go. I keep replaying the scene in my head. When I got home that day, I checked the back of my leg with a mirror, which is bad, I know. I found a tiny scab in the vicinity in question on my left leg, and decided to pick at it. It began to bleed a little, and then a long, ingrown hair popped out. I should have immediately attributed the scab to an irritation caused by the ingrown hair, but of course, it is still evidence of a needle prick from an HIV needle. I have stayed away from medication in recent years due to side effects. I used to take Prozac, but now it really upsets my stomach. I have heard that some meds make you gain a lot of weight. I don't know if I should discuss taking meds with my therapist because she can't prescribe them, as she is Master's level, although highly trained in CBT. Any suggestions?
