Trying to lose again after a regain.

My highest weight was 603, my lowest weight after surgery was 257.

I've gained 75 lbs back and I'm trying to lose it again.

I know I'm a stress eater and I eat way too many carbs.

i just got married in the last year and it's hard to get my new family to eat healthier.

also I've been diagnosed with Atrial Fibrillation.

I'm getting treatment for it and I've started exercising again.

Does anyone have any tips or suggestions?

I'm completely terrified that I fell in to old habits and I want to put a stop to it.

Thank you in advance.
