hiv scare and the longest 12 weeks of my life... did anyone else lose their mind

i'm about 7 weeks into a 12 week wait after a properly stupid night at a play party in sydney. condom failed, partner i didn't know well, alcohol involved, i won't go into more than that. i got on pep within 36 hours which the sexual health clinic were brilliant about, and i've had a 4 week test which came back neg. but i've still got another 8 weeks until i can really exhale. i've told dh everything and he's been a rock, no judgement, just here. i can't stop googling, i'm reading every symptom into something. has anyone been on the other side of this. how did you cope with the wait. how do you not let the fear ruin every day until the 12 week mark
