I Am Experiencing Dizziness And Hear This Noise In My

I am experiencing dizziness and hear this noise in my head that sounds like someone opening and closing the blinds. The only time I have ever heard this is when I tried to discontinue my anti-depression medicine (Zoloft) "cold turkey". I have been diligent in taking the medicine, but this problem has developed in the last few days. I feel like a "nut case".
