i want to be better

i want to be better. i want to stop the bad habit. i sometime just snack and eat without a stop. i want to change that. i know all the theory. but sometime i just can't control myself. i have made some progress. for example, i don't do grocery alone anyway in case i buy too much junk food. haha.

now i really need to work on -- when i am alone at home. i feel it is such a relief and such a quite time for myself. then i grab things to throw in my mouth, to treat myself. and it is not even a treat. it is punishment, i don't only feel guilty, but also my body feels bad, my head hurts, my stomach hurts.

i need to change. but how to do it better?
