Germ anxiety

I need advice. I’m constantly washing my hands after going to the bathroom/touching something I find gross, but it doesn’t stop at just washing. I have to keep washing til I feel right (usually 3-4 times). It also isn’t just my hands, I go all the way up my forearms. I know in my head that once is enough. But I can’t kick this repetitive behavior. I know I should just start only washing it once but I don’t know if I can handle the panic that will come after. I need advice/tips if anyone’s gone through something similar what worked for you. Im just sick of this

I started dealing with OCD when I became fixated on health issues, particularly the fear of contracting a life-threatening disease. If I experienced any kind of medical symptom, no matter how small, that even remotely hinted at something potentially fatal, it would drive me crazy, and I couldn’t stop obsessing over it. Then one day, I started having intrusive thoughts about accidentally hitting someone with my car, and I would end up driving in circles to check if I had. Eventually, I found myself overwhelmed by a flood of new obsessive thoughts and compulsions. One day, while I was at the park, a squirrel came near me, and for some reason, I felt like it attacked me. I Googled it and learned that squirrels could carry rabies, which spiraled me into a deep fear of rabies. I became consumed with the thought I received a bite from a squirrel, raccoon, or bat any time I’m in areas that trigger me. It started off only being inside then transferred to even being in my own home. This made me obsess over every physical sensation in my body, compulsively checking to make sure nothing was wrong. One compulsion that I hated the most would to be putting rubbing alcohol on me to make sure that I had no open wounds. Every day feels like I’m walking around in a fog of anxiety, constantly worrying that I won’t even make it to old age. Sometimes, it gets so overwhelming that I just want it all to end. It stresses me so bad at times to where my brain feels like I’ve been studying all day.
