Weight loss help

I've felt really insecure about my weight recently. my stomach is getting bigger than my boobs and I've always wanted to avoid that. but now its happening and i feel so insecure when i look down to see the weight I've gained. I'm truly disappointed in myself. i eat away my feelings or when i get bored and now its getting out of hand and i need to get it in control but i don't know how. I'm trying the hardest i can. i drink coke often and if i drink tea, it has about 2 1/2 scoops of sugar in it. and just everything i eat in geenral is unhealthy. anyone have any healthy habits to slow down eating or any good diets that will make me lose weight fast?
