Advice please?

Hey guys I’m pretty paranoid. This guy I slept with told me he had an std after the fact and proceeded to block me. We wore protection and everything but it’s the fact that he stopped talking to me and my paranoia getting to me. I told my friend and she said I’ll be fine. I booked my appointment ASAP but the only available spot is in 2 weeks and even the health clinic I went to today had a long ass weight.
