Hospitalization fear - I can’t get over the “what if” aspect!

Hello! I am really looking for some advice. I have been struggling with OCD for a few years now and it drastically affects my daily life. I am going to give a quick run through of my OCD, and then the current situation I am in now. So for almost 2 years now my most prominent themes of OCD have been getting sick with the stomach bug (emetaphobia) and watching someone die/ having to see large amount of blood or do CPR on someone (I just graduated nursing school). Last year I stopped eating out, wouldn’t touch any of my food with my hands, would wash my hands until they bleed every day, bleached everything I touched when I was in public etc… I would have these major panic attacks all the time and the thought of getting sick hasn’t left my head 24/7 for 2 years. I was unable to complete my nursing school clinicals due to panic attacks each time I was at the hospital afraid someone would die and get these terrible images in my head. I didn’t sleep ever, barely graduated. I did ERP after school and was able to make up the clinical days I missed. Got to a point where I was eating again, felt like I was able to get my hands clean just by washing them. I have been doing exposures every day, and have accepted that getting sick will probably happen at one point and I am okay with it as long as I am at home when it happens. So locking myself in my apartment for 48hr every time after I could have been exposed to the stomach bug is major progress for me and I have been overall doing much better. Fast forward to now: It’s time for me to start my new job on a med/surg floor in a hospital. This week I have made it through a few days of orientation with panic attacks day and night but I am doing it even though I am petrified. I don’t feel ready for this big of a step, being exposed to both of my biggest fears constantly. Today at orientation the girl sitting next to me told me she had been vomiting all day, and continued to run out of the room a vomit the rest of the day. I now am 90% sure I am going to get sick and feel as if I would rather die than continue this amount of stress and anxiety I have felt from just a few days of being on the job. This is my BIGGEST fear and it’s coming true and I don’t know if it’s worth putting myself through this every day at work to just be having constant panic attacks and be miserable. I know with OCD you have to face your fears but I have been pushing myself and trying so hard and I don’t feel like it’s worth it to work this job. I would also feel incredibly guilty for quitting on the first week, but there are a million other nursing jobs that are not in a hospital. I think this is too big of a step for me right now but I wanted to see what others think. Any advice at all is so appreciated!

Has anyone ever had an intrusive thought of thinking you’ve might’ve swallowed something dangerous and you can’t trust your own mind? And you feel like you need to go in to get checked out? Any advice or reassurance?

i’m terrified to get a diagnosis. What if it’s not actually OCD??? I made a list of reasons why i think so and then i think what if im lying and i actually don’t do this stuff and am just dramatic and i just want to have OCD so then my thoughts are justified?? I have struggled in the past year with Pocd & Rocd and then also some bits of thinking im constantly in danger or being watched? I’m scared.
