I am a 14 year old boy, and everybody in my family keeps telling me they think I am depressed. Usually, I feel very empty inside, and sometimes I feel so sad and unfullfilled that I feel like suicide is the only way out. I feel completely separated from everyone I used to be very close with. I am beginning to slightly lose my appetite. I have lost interest in almost all activities which I used to enjoy. Very occasionaly I feel very happy, but this feeling is then followed by sadness and emptiness. So, do you think I am depressed?
