I am not a happy person.

I don't like myself.  I don't like the fact that I have gotten lazy and motivated to exercise.  Something is wrong with me.  I am just depressed.  What is wrong with me?  I has been hard making exercise a habit.  I am thinking of buying equipment, but I wonder if that will actually hurt or hinder.  What good is it if I don't use it because of a lack of motivation.  I realize that I am in need of help.  I just need a push.
