exercise. i think exercise rather than restrictive eating is the way to go.

running or walking or biking or swimming.

that way... you build muscle tone. i'm not overweight technically... but i think i have a lot of fat. i KNOW i have a lot of fat. all squishy and yuk and best not go there... it all began when i had some injuries and couldn't walk the way i used to :-(

i had really toned thighs and butt and stomach from walking. now it has turned to flab.

if you get a cardio workout... then that is terrific for you in the sense that it gets the endorphins going (which is incompatible with depression too).

:-)

also... a workout can be a good way to vent frustration.

maybe... kickboxing or something?

maybe... your uni has a club?
