While many of the symptoms that you've described could be attributed to several auto-immune disorders, it is impossible for us to say if Lupus is a possibility. All auto-immune diseases have symptoms that are similar to one another and it is possible to have more than one auto-immune disorder at the same time (overlapping conditions).
I know that waiting for the results can be frightening and frustrating, but without those results, there is just no way of knowing exactly what is causing your symptoms. The diagnostic process is really a process of elimination and it can sometimes take months to a year before a final diagnosis is made. Especially given the fact that there are over 60 auto-immune disorders.
I would suggest that you keep a log of all of your symptoms and when they occur so that you can discuss this with your doctor. When you do get the results of your tests, please let us know what they are and we will do all that we can to explain them to you and to answer your questions. In the meantime, I am glad that you are here and please know that we understand your frustrations and your fears, most of us have been where you are. We are here to help you as much as we can.
Peace and Blessings
Look For The Good and Praise It!
