Sugar addict

Please help.
Im using food to buffer and it feels like I can’t stop.
I feel like a food addict. Its all im thinking about. Even as im going to bed tonight im thinking about what im going to eat tomorrow.
I’ve been dealing with some uncomfortable stuff at work and on the weekend I decided not to buffer but it was really hard to face how I was really feeling without the food or weight drama so this week im back in the food rather than feel the feelings. Im gaining weight and my clothes are uncomfortable but mainly I’m just looking to my next sugar fix.
Im so embarrassed that people will notice my weight gain but I don’t seem to want to stop eating all the junk.
I should know what to do, I lost all my weight 2 years ago, but it really seems I’d rather just eat.
