Anxiety over possible hiv

[Akwardguy]

Hi guys, last 2 weeks I had unprotected oral sex with another guy and he ejaculated into my mouth.  I was very scared and went to see a doctor and hold her about it.  She said hiv via oral is low risk and I didn't need PEP.  She took an initial blood test for std screening and all came back negative.  She asked me to come back again at the end of the month for another test.  I am very anxious and worried at the moment,  waiting for the day to come for my test.  I cannot function properly,  thinking about it everyday and cannot sleep. And I am starting to feel like my body is very hot and my skin has this burning sensation when I try to sleep at night.  I'm not sure how I can go though the end of the month.
Please help
