I'm sorry that you're struggling so much with the health anxiety right now
As a lightly hypochondriac I can relate. Exercise really helps keeping my mind calm...not always, but usually it works.
I also heard that CBT may help.
I hope things get better for you soon!
"We are told 'no', we're unimportant, we're peripheral. 'Get a degree, get a job, get a this, get a that.' And then you're a player, you don't even want to play in that game. You want to reclaim your mind and get it out of the hands of the cultural engineers who want to turn you into a half-baked moron consuming all this trash that's being manufactured out of the bones of a dying world."
