I USED TO LOVE EATING!!! but I AM NOT ENJOYING IT ANYMORE!!!

I think I am making it for death to take me easier. I am in a diet because of my cholesterol.
Everytime I feel better, I tend to eat foods that I should not eat.
I ate a lot for 2 days already, thinking I AM OKAY NOW!
I woke up this morning having a slight headache, then I was thinking HERE IT IS AGAIN!!!
As the time pass, headache gets on wilder :: it goes to the maximum that I feel like VOMITING.
I have to take care of myself... I have a baby to tend to...
I USED TO LOVE EATING!!! but I AM NOT ENJOYING IT ANYMORE!!!
HELP! I want food that taste good with NO / LOW CHOLESTEROL!
