I looked at your past paranoid posts.
... scared to death of door handles
... scared to death of being poked by needles on a subway
... scared to death of public washrooms
... scared to death of a pen handed to you by a police officer
... scared to death of a dog leash that touched the ground!!!!
Every time you post you're scared to death you've contracted a disease/virus (usually .H.I.V) from something innocuous.
Get professional help. If your therapist is hanging up on you, get a new therapist or get into an in-patient program.
I think the people in the .H.I.V forum especially have had enough of your paranoia.
