Im 19, 5'8, and 200 pounds... how can i lose weight fast?

im tired of looking in the mirror and thinking i look good then when i see a photo of myself i look like a huge monster...i thought i was okay with the way i look but its heartbreaking and hurtful when i see fit people. is there any way to lose weight fast and free. i dont have the connivence of a gym so that option is out... please no mean comments, im tired of faking being happy, im not depressed, its just hard to have self confidence looking the way i do
