I have

 I have ME/CFS that has no treatment or cure and only gets 5 million dollars for funding a year. It complicates other illness and it makes you feel like the living dead.  

I have severe pots but I'm treatment resistant so far so I have to constantly be in a recliner or my reclining chair. Most Drs don't know how to treat it properly. 

I have fibromyalgia which has only one treatment that doesn't work for me. My Dr specializes in fibromyalgia and said I have the worst case she's ever seen.

I have Hashimoto's disease and almost no doctors have any idea how to get the antibodies down and are just concerned with my TSH levels. 

Two doctors think I might have either lupus or ANCA MPA Vasculitis. MPA Vasculitis is very rare but I have the antibodies and now my lungs and kidneys aren't right. I have too much creatinine and bilirubin in my urine. I have too much creatinine and too little of EFG or whatever the acronym is in my blood. I have had a chronic cough for years and I have been wheezing loudly since at least January. Now I have a collapsed lung and pneumonia and while Matt and my friends who were over also got very sick, none of them got pneumonia. Just me. Only about 9 out of a million get MPA Vasculitis. Treatment is heavy immunosuppressants. Only 80 % survive the complications of the first 5 years. That's about 2 out of every 10 people dying within 5 years. And because the illness is rare it's hard to treat. The people who survive go into remission but there's more than a 50% chance of relapse. It affects your immune system, kidneys, lungs, nerves, and joints. A lot of people end up needing kidney transplants. My Dr is almost 100% sure I have it and she's not the first to say so. They just aren't allowed to confirm it with a biopsy of my kidney or lung before they start failing and now it looks like they are.  

Finally, I have complex PTSD and I am in survival fight mode 100% of the time. It's exhausting. I cannot fully trust people. I cannot fully accept love. I have insane abandonment issues. I am always preparing for the absolute worst. I have an obsession with what's fair and what isn't. It's extremely hard to have and keep close relationships. I'm irritable all the time and extremely controlling. I have flashback nightmares every single night and I act and talk them out so even my dog doesn't sleep in my room anymore
