First of all, don't listen to the moron before, I mean honestly that is so irresponsible it isn't funny,
As for the the case, I am only a medical student, but I have a medical science degree with honors and some psychology training, so my advice isn't as a medical doctor, (yet)
Anyhow, while the description you have is vague, it sounds quite typical of schizophrenia (Auditory hallucinations etc). The first thing you should do is don't panic, and try to be level headed, try to ignore any thoughts that seem bizarre or illogical,
Another typical symptom is paranoia, you may feel inclined to feel that society or a secret organization is plotting against you, just ignore those feelings as it is the disease talking
Secondly is get yourself in to see a doctor or a counsellor/psychologist as soon as possible, don't worry if you see the wrong type, as they will know who to refer you to
Again don't worry, usually this can be controlled with some simple medication
Good luck and I hope you get well
