Thank you everyone for your help. I finally decided to get some help for my anxiety. I will also be seeing a counselor regularly when I go away to school this Fall. I have been suffering from axiety for a while now and I may also have OCD. I often find myself checking to see if I unplugged my hair straghtener about 5 times before I leave the house and before I go to bed at night I check the door locks repeatedly. Everyone here and also my doctors had told me that I am negative so I don't see why I shouldn't believe them. I guess I am just stubborn and in the back of my mind I think of my symptoms after my 2 and 4 month negative tests and also contantly think about the historical 6 month window period. Thanks everyone for your advice.
I am just still curious if anyone has facts:
When was the last time someone took longer than 3 months to test positive? And did they have a medical condition such as cancer or IV drug user?
How long ago was it when they say 6 month testing is "historical"? and now the definitive test is 3 months?
If anyone knows this I was just curious in knowing...Thanks everyone, with your support I am doing a lot better.
