Start working out at home until you are comfortable to do it in public. There are a lot of workout apps to download. That's what I'm doing. I lose 2 pounds this week. Went from 268.8 to 266.8. Keep up the good work. As far as stress eating because I do a lot. When I get stressed and start thinking about food, I stop and pray then put the money that I was going to spend on food in my savings account or toward a bill.
God bless and Jesus loves you all! He stands at the door of this life and knocks and a waits for you to open it and let him in. What good is it to gain the whole world and loose your soul in eternity in hell. No matter who you are, you can come to know and experience the true love of Jesus. You can ask him right now, out loud, or in your head, for him to help you to believe in him and have faith he will help you!
