I'm guessing you are feeling depressed from some underlying reason or under stress which would be understandable in your situation? either way, this board is not the best place to seek advice, well meaning though it all is.
Go see a Doc ASAP, he/she is qualified to help you better, and has the experience to diagnose the root cause of your problem and prescribe a remedy, it doesn't always need medicine.
Wont cost you anything, do it.
