New, looking for info

Hi, I'm Erin and not sure where to turn. For the past 1 1/2 years I have been having strange sypotms. I have been to my Primary Dr. and refered to many others. No answers yet (they just keep refusing to different Dr) I feel great at times, then for no reason I feel "funny". It's hard to explain, but I will try. My vision gets fuzzy (can't focus without trying really hard), I get dizzy/ lightheaded, and the top of my head feels heavy. Just last week I felt as everything around me was in slow motion. I could see and hear peolple talking to me, but felt like there was a 2-3 second delay for me to understand and longer for me to respond. After that I felt "off "for 2 more days (tired, slight headache, balance felt like I was drunk) then day 3 everything was normal. Thank you in advance for ANY info you have. Tired of being bounced around....wanting answers.
