Do I need help.. is this anxiety?

Hello.. this story is long and boring so If you don't want to sit through it I understand.  Okay... 3 years ago i had a false positive hiv test (it was really really scary) since then I have seen two hiv specialists and been tested about 20 times.. I had such a bad fear that the one test was right I went to every single clinic where I lived and tested negative over and over.. The doctors all told me to move on I was ok.  So.. I needed a change of pace and I moved out of town to a new city and got a new job.  Well that was 2008 and for a year I was doing great..maybe very good not great.. anyway I have not had any SEX at all since the false positive test.. I will not even have protected sex or get into any relationships.. But the real issue is I now have a friend/co-worker who I found out is HIV POS.. what are the chances right.  Well.. we work togeher almost every day and she always is chewing her fingers and rubbing her eyes and she often has little scratches on her hands from her pets.  I am so upset because I think oalso I just worry that if I get any blood even a speck that I don't see that i might rub my eye (eye is mucaus membrane) all this stuff.. I know all of these things are not really ways to cathc it but i am just so PARANIOD of hiv that it is ruining my life.. should I get another job.. should I try and see a doctor.. I don't have insurance and cant really afford either.. how has this happened to me please some advice.. ANYBODY ARRRRRRRRR!!! thanks for any help f all these ways I could catch hiv from her.. Like she had a small cut on her hand and we shooke hands and I got scared..

Unless you have unprotected anal/vaginal sex with her, your risk is ZERO.
And forget the cat scratches and finger chewing.........NOT A RISK!
Find the money SOMEWHERE to get yourself into therapy! Look what this totally irrational fear is doing to your life!
MOVE ON!
