I don't know what to do anymore

I don't even know where to begin. I just feel an overwhelming sense of hopelessness. I've had long-covid since Jan 2022 and it's just been one thing after the next. There was a period between end of last year and early part of this year where I thought I was turning a corner, but I feel like I've suffered a major relapse and now feel even worse than I did last year.
The migraines are the worst they've ever been. My insomnia has returned. Extreme joint/muscle pain. Major GI issues. Weird rashes. Chest pain. Red hands and feet. I just feel like it's a never ending nightmare, that most people don't understand. Unless you've suffered or still suffer from LC, most people don't get it or they think you're making shit up.
I never used to be a hypochondriac before LC, and now I constantly live in fear for my health and life. I worry about chronic diseases, cancer, heart attacks, blot clots... just constant worry that I'll die from this.
I don't know what to do anymore. I am grateful for being apart of this LC program at the U of M. I've seen countless specialists. It's comforting in some sense to get checked and to have doctors that try to help you figure out what's going on. But when tests come back normal, you feel back at square one. And you're still in pain. I just wish I could feel normal again. I feel like I don't even recognize myself anymore.
Thank you for taking the time to read this. I have found that reaching out to others with LC does help. I wouldn't wish this on my worst enemy. But there is some comfort in knowing that there are others out there who understand.
