This is a natural process with which the sperm stored within your body is released once you do not masturbate or engage in sex. To clear this, practice masturbation or sex thrice or four times a week. Premature ejaculation can be physical or psychological. As you said it is from your adolescent period, I suggest you to consult a urologist for investigation. You could need treatment. Watching porn clips, masturbation etc. are not unhealthy processes. You should watch they should not become habits. Depression is a euro chemical disorder and is usually treated with Chat Doctor.  Consult a psychologist.
