mixed connective tissue disease, rheumatoid arthritis and fibromyalgia

I'm a 46 year old female with mixed connective tissue disease, rheumatoid arthritis, fibromyalgia, diabetes and latent tb. My symptoms off all of those things came on slowly and one by one. I currently take a lot of medication. On a good day I can walk almost 2 blocks. Other days can barely manage to stand at the stove to cook a meal. I had had some mini strokes in the past that get irritated and mess up my memory. My legs hurt and the bottom of my feet meat feels swollen. So many symptoms that at times the drs look frustrated. Need help and ideas. Want to get better enough to work again some day.
