Young bro, if you are on facebook, add me and we can talk. I get this often and it is NOT nice at all.
For some tempoary sanity go to your doctors and whatever you do, DO NOT please do not get any anti depressants, they only worsen the situation, nbeileve me i have been there on a high dosage of fluoxetine hydrochloride (prozac) and a number of others citalopram etc.
The only thing which will work beileve it or not... is diazepam. Valium.
Be very CAREFUL not to over do it though, because it can lead to addiction to these tablets. Whenever you feel down and depressed, just take one 5mg tablet and you will be fine after that.
Do this for a month or so, but only take it when you really need it, because again, it WILL lead to an addiction.
This worked for me and i am fine :)
