Welcome, Yes you are one of us. It is overwhelming at first. It looks like you have many of the neurological symtoms of celiac. The unidentified white spots are one. It also sounds like you have Dermatitis herpetforma which is the skin form of celiac.
I have had a few times where dizziness was a side effect for me.
It is best to start simple. As long as you just eat whole foods meats, fruit and vegetables. you may have to drop dairy for a while because the villi that absorb the lactose are damaged and need to heal.
You will need a new toaster, pasta strainer and wooden spoons etc. Condiments are another issue. You need your own that has not touched wheat bread (mustard, mayo, butter, peanut butter, etc.)
It will get easier as time goes on. One more thing all first degree relatives need to be tested.
Hope that helped.
