Addicted to Fast food

Hey everyone. I've struggled with my weight for a few years & although I don't really look like I'm very overweight, I am ( I just carry it pretty well). Anyway, the reason I began gaining weight was because of self-esteem issues stemming from a bad relationship and since then I haven't been able to lose it. I feel really bad about myself sometimes, sometimes I feel good about myself, but lately I've completely fallen off the weight loss "wagon" and have not been to the gym. Also, I can't seem to stop eating fast food/junk food, and this is also making me feel bad. ON TOP of all this, I really don't have anyone to talk to because as supportive as my new boyfriend tries to be, he just doesn't understand like another girl could (though bless his heart he tries). I just wanted to share this with you, and maybe see if anyone else was in a similar situation. This is hard for me to post because I'm generally a very upbeat happy person, but sometimes keep things inside. I need some support, and some friends to try and lose this weight and be healthy once and for all. Thanks
