For the last few weeks I haven't been feeling quite myself. The best way I can describe how I'm feeling is asking if you've ever watched a movie and noticed that the soundtrack isn't matched up with the picture. I feel like I'm drunk, but I'm sober. It's really scary for me at times and I'm not sure what to do. I eat healthy, I exercise, and I get plenty of sleep. I'm 5' 5" and I weigh 137 pounds. I gained 8 pounds over the last month or so, but I honestly think it's muscle. I'm terrified that I have a tumor or some sort of abnormality in my brain.
