I have become paranoid about everything I do because I don't want to contract HIV... examples:

- I just shaved, and I washed my razor blade, but for some reason I still feel like I somehow got it due to my roommate POSSIBLY using my razor. Though I didn't see any blood

- I cut my hand in the elevator = I got HIV

- I bumped into someone outside = I somehow contracted HIV from some blood on them

The biggest one has been the shaving one. I am afraid to even tweeze my eyebrows because im afraid my roommate used my tweezers. I can't even leave my toothbrush in the bathroom. My roommate even says he has gotten tested and doesn't have HIV, but I can't believe him because im so worried :{

advice? I CANT TAKE THIS ANYMORE!
