ANYONE with experience of Auto - immune, thyroid, lupus or rosacea?

I think I’ve convinced myself that I have a high chance of a positive blood test result…

main problem presenting is the rash, and face swelling for 24 hrs
I have had hypothyroidism diagnosed a year ago, I had labrynthitis about 4 years ago (vertigo) or so I thought… Balance all in all not always been brilliant last several years I’m 40
Relapsing cycling worsening rash on face, slight liver pain sometimes, very dry eyes (tested) dry mouth, joints mainly okay apart from wrists on and off all my life, also fatigue, does come and go, but spent years napping and generally feeling tired, nothing that’s got a lot worse but I’m on disability with schizophrenia anyway so fatigue less of a problem because I can do less anyway
After one or two days of huge activity I’m flattened lately though
Possible onset of worse headaches though lasting for a few seconds or minutes, don’t know if that counts
Low and borderline white blood cell count, heat rash ie through jeans on legs…
Have had some hair loss a long time ago, for a couple months, palpitations a few times a couple months ago , slow resting pulse (60)

Lots of bitty things, I could also mention pain on deep breath sometimes and shortness of breath after stairs but I think I’m clutching at straws

I am always looking up symptoms but this time i have really bad rashes on my face as well as swelling on my face,
it’s not there right now, but i’ve shown a gp pictures and he said to see someone as soon as my face goes red again,
every attack i’ve had this year ( rash ) has been worse than the one before
