Possible Autoimmune Disease Diagnosis: Seeking Advice

Ok so I just found out that I maybe (?) don’t have lupus, but I definitely have an autoimmune disease. My last doctor was very awful and I now I have a new one. Basically I got diagnosed by a blood test (which even if it’s positive, doesn’t mean I have lupus) and like I said awful doctor, did no other further testing or tried to send more over to proper doctors like a rheumatologist. Now my new did another blood test and my ana (I think that’s what its called) was negative, but the other one (idk what it’s called) for an autoimmune disorder was positive and I have all the autoimmune symptoms, etc. Idk what to do,,, I have to wait a long time to get further testing at a rheumatologist or whatever. I honestly just what to know what k have,,, I think I might have Fibromyalgia m, but that’s not an autoimmune disorder 😔 anyways, any advice? Also thanks for reading this long blurb of text 😭
