I really, really thoroughly recommend seeing a therapist and perhaps your psychiatrist (assuming that's who prescribed you the klonopin and zoloft).
for one, maybe the zoloft isn't the right medication for your OCD! you may need to try another medication for OCD. i believe some others are prozac and lexapro.
secondly, i am in therapy for a VERY similar situation as you. i also have a very intense fear of HIV. instead of trying to guarantee that i am safe from all those diseases, i am working on becoming comfortable with the uncertainty. the likelihood that you contracted HIV from the situation described is extremely unlikely, however OCD convinces us that there is some slim chance that it WAS possible, and the OCD becomes fixated on that tiny probability and we want to know for 100% sure that there is no chance, which is silly because there is no way to 100% protect ourselves and feel entirely safe when our OCD becomes fixated on such tiny, slim probabilities of contracting diseases.
( I am, naturally, speaking on behalf of my own experiences and feelings, but I feel that you may understand/relate to this. )
anyways, now in therapy, I am working on becoming okay with the uncertainty. it is very anxiety provoking initially, but i think in the long run it makes our lives a lot more enjoyable with much less anxiety.
i'm not really sure if this helped/made any sense, but i hope it did. i also hope that if you have the ability to do so, you seek help with a therapist and/or psychiatrist for your OCD. i wish you the best of luck!
Can someone please help me? I'm loosing my mind, please? Nurse girl?
