Obese Girl Looking To Get Healthy, Hello!!

I am newish to MFP because I downloaded the app and signed up a long time ago but stopped using it after a year. But here I am back again on MFP starting back up again logging in my food. I have been morbidly obese in the 400s for over 10 years now and I want to become a healthy 200 pounds. I have problems with binge eating on junk food, being a sloth when it comes to walking and strength training, and being consistent with my fat loss plan. I know what I need to do but I procrastinate and slack off lots of the time and all this has lead to me being 468.2 pounds, sedentary and unhealthy. I am starting my fat loss journey because I want to go out into the world and serve the lord and express the holy spirit. Hello fellow MFP members.
