I can't eat healthily!?

I know I should be eating healthily but everyday I end up eating so much junk food.

I'm a uni student, so limited funds mean that whenever I eat out its usually take-away crap instead of proper meals.

If I eat healthily for the morning, I feel like I deserve to eat something bad/overeat in the afternoon.

Is anyone else like this?

I am not overweight... I just eat crap. Any advice?
I know how you feel. I barely eat anything all day long, then at night I eat whatever I feel like (junk.) I do worry about how it's going to affect me in the long run.
I do however, take vitamins (pre-natal) because they have more iron and other things in them than regular multi-v's. Also I drink Ensure and try to drink a lot of water and 100% juice. These are some things in the right direction.
