22F Lupus Concerns

22 year old female with an extensive family history of lupus, displaying symptoms such as:

-Heat intolerance/heat rash/sensitivity to the sun (visually as well as physically)

-fingers turn purplish when cold

-poor circulation to extremities

-unexplained joint pain (mostly in knees and ankles but as I get older is beginning to appear in my wrists as well)

-unexplained fatigue (this will just hit me out of the blue, causing me to feel as if I could fall asleep immediately no matter what I am doing at the time)

-occasionally heart palpitations strong enough to make me uncomfortable

-inability to take a full breath of air since the age of about 10

I also have been diagnosed with several mental illnesses and am taking a few different psychiatric medications for these, however I chose only to include symptoms that I have had since I was a child before I ever started taking any sort of medication. This list of symptoms is unexplainable and I have never found answers. I had a rheumatoid arthritis test done as a teen due to concerns over the joint pain but the results came back negative. Joint pain so severe that as a child I would wake in the middle of the night crying and would not be able to fall asleep the rest of the night. It is still this severe, however I am fairly used to it now after 20 years of feeling it.

I am posting this here out of concern that I may have lupus, which runs heavily in the maternal side of my family. Money is tight as I am in my early twenties lol, so I wanted to have advice on whether I should go to get testing done. I will include a photo of the heat rash I get, unfortunately I don’t have one of the purplish cold fingers though. lupus rash?
