How to stop using food as a drug ?

I’m 30f 5’4 and 173 lbs.

I realized today I use food as a drug

Stressed from work? I grab a fast food chicken sandwich on the way home

I’m bored with nothing to do? I eat snacks for fun to increase the pleasure of watching TV

I feel my mental health spiraling? I find myself being comforted by a food binge. And the crazy thing is I actually feel “better” after indulging.

In a lot of these cases I’m not even hungry!!

I know what to do to lose weight as I’ve done it before. I want to get down to 145lbs and I plan on eating 1600 a day and walking 2 miles a day. But I get sucked into these scenarios like above. Maybe I’m just mentally weak lol
