Anyone here with health ocd? / hypochondira?

I keep thinking i have this and that and i kinda believe it… Like yk i kinda always think my thoughts make sense. 😭

I‘m not kidding at 7 i thought i have brain cancer. Like i was convinced, i knew i‘d die soon, etc. (saw it on TV). This kept going until i thought i have cervical cancer, breast cancer, hernias, appendicitis, colon cancer, thyroid cancer, pneumonia, so many heart attacks, lung cancer, dislocated discs, hEds, liver failure, etc. (Unfortunately i have a wide spread medical knowledge due to my mom being sick all my life already)

Every time this spiral keeps going until i am absolutely breaking down, sobbing, knowing „my time has come now“, writing letters, imagining my funeral etc.

I literally can not keep doing this it‘s burning me out.😭

How do i break this cycle. I‘m currently experiencing a new symptom and promised myself to this time not google or look it up ANYWHERE (chatgpt, reddit, tiktok etc). Is this how it‘s done? I really just need some guidance here. Thanks i advance🩷
