I know exactly how you feel, and to let you know, it is possible. I was 175 pounds and am now 145 pounds. I lost all that weight in about a year. All i really did was count calories (limiting myself to 1550 a day) and exercise about a half hour a day. Just give yourself time, and you can do anything you set your mind to. P.S. I'm 5'2", so i really was fat, i still am, but not as much as i was.
