Complex, wasting, unknown spinning wheels.

Hi I am new and at my wit's end. Told husband today I'm going to Mayo because I hear magic is done here.

Don't know where to begin. I will try to keep this basic.
Symptoms, falling, weakness, walking and standing limits are about 10 minutes before I start to feel faint. skin lesions severe dry skin, hair loss, double vision, dry eyes, gritty eyes, migraines and chronic daily headaches, confusion, dyslexia, memory and other LDS, I do movements all day long like restless leg, depression, bipolar, anxiety, agoraphobia, ocd, social anxiety, ptsd,(child abuse) panic, chronic pain, HORRID FATIGUE, apnea constipation, diarrhea, acid reflux, problems swallowing, seasonal and environmental allergies, my heart feels like it's beating out of my chest, also I don't exercise because of fear of falling, but whenever I exert myself in any way my body starts throbbing and in less than 30 minutes I feel like I'm going to faint.
Diagnosis thus far thyroid disease, diabetes, migraine, high cholesterol, high blood pressure, gastroparesis,

The most recent thing is my brain is full of lesions, and my ventricles are enlarged, atrophy and one of the one ventricle is larger than the other. Ms specialist jumped in right away.

Here's the problem. As always for the last 30 years been trying to figure out what's going on and nobody has answers. All I know is this if the lesions keep progressing it's going to take my life. I mean where do I start?
