Connecting the Dots

Things in my life feel a little disjointed. I feel like a haze is floating around me like a bubble. I take Zoloft for anxiety and depression and OCD, and I have no clue if the meds are causing me to feel this way. I'm having a hard time seeing the bigger picture of life. My grades suck, I feel emotionally closed off, I'm far from home, and I have no clue how counseling is supposed to help. I don't know what my purpose is at all, or what I'm supposed to do with my life. Any advice on how to deal with these things, how to be enlightened, or what I can do?
