How many autoimmune diseases can you have?

I have just been given my 8th autoimmune diagnosis. For the love of GOD 🙏🏻 how many can one person have? It’s exhausting 😴 to say the least. And they’re all rare ones . Go figure. And no one in my family has them but they tell me that it’s hereditary. I read it’s extremely rarely for ppl to have over 5 …. Really….well lucky 🍀 lucky me! 🙄 does Mayo Clinic ever do consulting on a pro-bono basis? I’m quite positive they don’t take my insurance….🫤
