mental break down

im not too sure what has happen to me but i felt as though ive been drugged, being all paranoid and having this mental break down is really scaring me. Thinking of suicide and all isnt right at all. I really need to get a grip of myself and not let this loneliness control me and making me see things or hear them. I really need to get back to KL. I cannot stand staying here, im not sure if its pressure or loneliness but either way i need to get myself back home.
