ever since i can remember iv had this weird thing about feeling fat..and like, if iv had a big meal, i now (habitually) breath in and suck my stomach in really hard for a few seconds, and i often repeat this..also with having ocd i kinda twitch my anus and like make this weird feeling go up my body cos i hold me breath..sorry, this sounds so so messed up, but im just wondering if iv brought all my pains of myself, from doing these things..and im scared iv like caused myself cancer or something:S
