constant worry

i don’t know if this is where to post this but?? in april of this year i gave my boyfriend a blowjob (yikes) and like ever since i’ve been so scared of getting an std. we were both virgins by the way. i don’t think i was mentally ready for this. like its been months but every time i get the slightest sore throat i cry all night out of worry. i am a diagnosed hypochondriac so obviously that’s part of the problem. but it consumes me everyday? it’s been months since i even did it and every little sore throat leaves me with a panic attack. i am so terrified to do anything sexual again because i can’t stop worrying
