lyme lupus or ms?

I have been through heck trying to get what I have wrong diagnosed correctly! I was first diagnosed with lyme disease, and then neuro lyme and told 6 yrs later that they didnt think it was lyme at all! Then sent to rhuem who tested me for lupus which was negative, and sent me to neuro who ruled out ms with one negative mri. Then my rhuem treats me for lupus anyways for last two years. I had numbness on left side of my body and trouble swallowing, was sent to er who said oh its just flare, but when I went to my primary who did another mri of the brain found two lesions one on front right lobe and one on front left lobe, and now i am back to neuro. I am not upset with Rhuem hes treating me to try and slow whatever it is. I do want to mention I have a sister with MS, and sister with Lupus, as well as 6 other relatives with lupus. I am just tired of not knowing what I am dealing with! Another embarassing symptom is hallucinations! i dont hear anything just see stuff, I know its not real but it is annoying. Please help!
