Oh no, I'm so sorry to hear that! You know, I'm only 24 and I feel the way you do sometimes. Especially after a long weekend of "partying". I get that guilty depressed feeling. I totally feel you though. Sometimes you just know and feel that there are so many other important things to be doing. And you are right, there is nothing wrong with the way you are feeling. It's natural. I suggest, take it easy for a while. That's what I'm doing. The summer drained me. It was my first summer with a shore house and it was alot crazier than I expected. It's ok to have a good time, once in a while. you know!
