Here's my thought on fatty, carby, sugary comfort food.
You might as well sit on the plate, because that food is going to end up on your butt anyway.

No, seriously, this is a conscious choice to get healthy. There is ALWAYS going to be something that could be an opportunity to trip you up, but it is your decision to make it through, or give in.
Families don't always come on board when we try to lose weight, and many times, they will subconsciously sabotage your best efforts. You will always have a social engagement where the foods offered are not on your list. Birthday parties pop up, special occasions, holidays, etc.
If you have a favorite recipe, go online and find a lower fat, lower sugar version of it. Find lighter versions of foods you enjoy, and stock them. Don't buy snacks or trigger food, and if your family protests, have them put their stash where you can't get to it. I have certain "comfort" foods that I don't have in the home, because one bite just isn't enough.
It's just about your mind set for the most part. This is a journey that isn't always easy. And to be successful, yes, we have to give up some of the foods that got us here in the first place. But it is worth it when you start to feel better, when you can button up your pants without having a "muffin" top, or having to stretch out your t-shirts so they don't cling to your belly.
It is worth it to do this, and do it for YOU. Find another source of comfort. Hot tea soothes me, and I drink that to avoid late night snacking.
Good luck in your journey. Keep strong, and take care.
