Hypochondriac and severe anxiety- so stressed and feel stuck what should i do?

My name is Zoey I’m 22 years old and I have struggled with severe anxiety my whole life. I have been a hypochondriac before and it comes and goes. Lately due to Covid-19 I have been going back to my hypochondriac ways. I worry about stds and have been tested multiple times and it always comes back negative ( its been 5 months). When I worry I feel like I have to check constantly and feel like something is gonna change daily. I noticed that I would freak out after my meds wore off for the day. I feel like this part of my life came to be when 4 years ago my ex cheated on me and gave me clyhmydia or however you spell it and my health anxiety has gone away for a while. Tonight I got myself freaked out and had a full blown panic attack and I brought myself to the hospital cause nothing else was open and I thought they may be able to help me. They gave me this nurse practitioner whom I have had before, and he just told me take another dose but told me he refused to check the symptoms cause they were just in my head, he treated me as though I was insane. does anyone else ever feel like that and what do they do to help it? I feel so stuck and anxious.

hi,

me and my boyfriend havent been intimate in almost 3 weeks because of it, all because of this:(
