Hi. I am 24 years old and feel depressed/or upset very very often. I don't know why. I have always been somewhat of a moody person, however, the mood swings have gotten worse over the past year or two. I don't mean to have these negative feelings, but I try to occupy myself with positive things in my life to get over it..but regardless of what I do it still seems to linger especially around the premenstrual stage. I find that because of these mood swings, I don't feel like doing anything, and have a hard time concentrating or focusing on anything. I don't want to use prozac or any drugs that might make me feel codependent upon but would like to do something about these unwanted moods..please help.
