What Causes Dizziness While Suffering From Depression?

Hello, I am unsure what is causing me to feel distant and somewhat dizzy. I thought I had depression, but the pills make me worse and I don t struggle with constant sadness, my issue is constantly feeling distant as if I am in a dream. My dad had diabetes, but I have normal sugar levels when I get blood work done. I seem to be constantly thirsty, needing to drink more than 32oz. of water alone, but feeling thirstier if drinking it all in a short succession of time. My bowl movements become atery when I drink more than 32oz. a day, but is hard when I dip under 32oz. of water. I do not smoke, drink alcohol often, or drink coffee. Please help. ~S.Parker
