What happen to my life???

I am suffering from mental sick.... I feel very upset... I have no confidence to myself, I need someone to talk to... Nobody can understand me.... What I can do is turn the volume to the loudest, and wear on the earpiece.... I do not want to hear any word from anyone, I want to hide myself in a small room, a corner... any place that no one can notice me... I need a peaceful place... quiet and nobody can see me.... At there I do not need to bother about other's feeling, view.... I can be "myself".....

What can I do now? I am just a stupid human... know nothing.... I am a looser...
