I agree that you do sound depressed. Check with your school to see if they have a counselor or therapist that you could talk to. They'll be able to help you in ways that our forum cannot. You can work on your possible depression and self esteem; two things that, more often than not, go hand in hand.

Also, you are only a freshman in college. There is no need to stress at this moment about what you want to major in or what you want to do with your life. Take your gen eds, read course descriptions for upper level courses, maybe visit a job fair to see what kind of jobs are out there, and then find something you're passionate about. I used to get very anxious and depressed when I was in college and had a lot of trouble motivating myself. You have to do these things at your own pace, or you will not be doing them for yourself. When you are doing it for yourself and not to appease others or society, you will have motivation.

Perhaps you can make a list of your good qualities, write it down, and read it and try to add one thing to it everyday. (Ps, an 8 pack? That's too much of a good thing). Maybe if you got involved in a social sport on campus. Intermural sports, or something like a flag football, ultimate frisbee team. Something not to serious to get you moving and out doors. That will help with depression and make you more confident.

Once you believe in yourself, every thing else will start to fall into place. I know it sounds corny, but it's true. I would strongly recommend talking to a therapist to help you out.
