Is anyone else struggling with health OCD and constant exhaustion?

I’ve struggled with health anxiety for about 11 years, and it’s been horrible the last 3 years. Health related stuff wasn’t my first theme though. It started out with contamination OCD and magical thinking, and then I was diagnosed in 2015 after being hospitalized. Throughout the last 5 years or so, I’ve been hospitalized a few times for debilitating health anxiety OCD, been on countless meds and struggled to find an OCD specialist. I just want this nightmare to be over. I’ve been convinced of having breast cancer, lymphoma, bladder cancer, brain tumors, ovarian cancer, skin cancer, cervical cancer, and many other health issues. I’ve been to the doctors multiple times, I’ve demanded tests, I’ve compulsively gone to the ER and urgent care to “check” for reassurance, I’ve been convinced that doctors aren’t looking good enough or are lying to me. I do a lot of body scanning, and reading and rereading doctors note for reassurance. I also call the doctors office a lot. Again, I just need this to end but I don’t know what to do because I am so burned out.

So I’ve been suffering with intense health anxiety for a few years now, and just recently I learned it may be caused by OCD. It’s to the point where every time I get a headache I start to freak out, scared that I could be having an aneurysm. I am far too worried about having a stroke or heart attack for being 21. I can’t even enjoy a casual, relaxing hot shower anymore. I have to slowly increase the temperature when getting in and slowly decrease the shower while getting out because I am afraid that any drastic temperature change can give me a heart attack. I know deep down that these fears are illogical, but no matter how often I get them they still feel just as real every time. I try to reason with myself, but every time I feel mild discomfort in my body I can’t help but freak out. I am so tired of checking my face in the mirror for symptoms of stroke every time I get a headache or feel a weird sensation in my body. Every other day of the week I force myself to stay awake for a certain period of time because I’m scared if I go to sleep I won’t wake up. I get hymnic jerks every single night (where you jolt awake when drifting to sleep) because my brain is so occupied with making sure I’m staying alive that it jolts me awake because my body is trying to sleep while my mind stays awake. It’s so difficult for me to pay attention during lectures because I get so caught up in my health anxiety that I’m focusing on grounding techniques in order to keep myself from hyperventilating. I spend more time making sure I can understand the words my professor is saying to make sure I’m not having a stroke than actually paying attention to the lectures. Another thing I struggle with is having to count my medication every time before I take it to make sure I didn’t accidentally take two or more doses, even if I KNOW I only took one. I have to count them anyways otherwise my mind will convince me I overdosed. It will not stop until I count my medication and make sure I didn’t overdose. It’s honestly so tiring, and the sad part is that my health anxiety has actually gotten better. It was even worse before now, and everything I’ve listed is stuff that I still do. Does anyone else have this struggle? Because it feels so isolating and makes me feel like I’m going crazy.

Recently my ocd has been directly exasperating my health anxiety and it causes daily panic attacks. I’m tired of feeling like I’m dying every day when I know I’m physically healthy. Does anyone have any coping mechanisms for this?
