I'm always feeling depressed. Even though there is any particular reason I always feel sad . Always crying. I can't control myself. I can't concentrate in my studies. No interest in any activites . I feel loneliness. I can't explain what I really feel . I had same experience when I was 7 or 8 and lasted till my 5th grade . After our shift to hometown, I started feeling ok. Then from 9th grade when we shifted to another again I started feeling same. At times I used to self hurt .
