Hiv Scare, 17 Year Old.

Like another poster on this fourm I did the exact same thing went to an escort used a condom for sex but not for oral. I messed out about it for a couple of days thinking I caught hiv, told my mum and she said there was nothing to worry about. 3 weeks later (today) I have contracted flu like symptoms and prior had a dry mouth for about 3 days now i'm going out of my head with worry. I dont know if i'm doing this psychological to myself but i'm so anxious and scared. The escort told me she was new and I was her first client, 2 people have told me that she was probably lying but all I can say is shes seemed very genuine and inexperienced. I'm only 17 and hope that this isent the mistake that will define my life. Althought the thought of having contracted hiv makes me feel suicidal all I can say is that i'm thankfull I live in the uk were drugs and care will be provided for me to live a normal life if the worst should come true. I know that getting tested now will probably not show up anything but I just need some kind of peace of mind even if its not real. Finaly I will follow up this test 2 months, 3 months and 6months since I had sex to know for sure.
