Hello and Welcome;
I am sorry to hear that you've been struggling so long with this illness without a diagnosis. I cannot suggest anything better to you than what SleepyInSeattle has said. I just want to stress to you to please, please follow her suggestions. It is very dangerous to stop taking your medications without your doctor's OK and his guidance. Doing so can be a fatal mistake! So, please continue to to take your medications.
Hopefully, you may not be diagnosed with Lupus. But even if you are diagnosed with another auto-immune disease, it remains critical that you take your medications as prescribed.
We are here to help you in any way that we can. Also, please know that when you are here with us, you are not alone. You are amongst many who truly care, who understand, and who want only to help you as much as we can.
Again, please start taking your medications immediately. Take care of yourself and know that we are here for you.P
Peace and Blessings
Look For The Good and Praise It!
