I Drank Quite A Bit Two Saturday's Ago And Have

I drank quite a bit two Saturday's ago and have been slightly dizzy for almost two weeks now. When this happened before the doctors said it was dehydration but this time feel like I'm drinking more than enough water. It's really bugging me and giving me panic attacks because two weeks is a long time to feel like this. All I do is lay in bed now because I'm too scared to pass out at the gym or something.
