First of all Congratulations on your weight loss so far. That is no small feat. It is very important that you continue to work on you. With all the past medical issues, taking care of your body needs to be a priority. Some suggestions to consider: plan and prep your meals at the beginning of the week so they are easy to just grab and go, keep bottled water and protein bars in your car as backup so you will always have an alternative to soda and fast food, park far away to walk more, take the stairs, walk during your lunch. Any small step is a step in the right direction. Don't give up. You are worth the effort! Also finding a way to let the stress go is important. Pray, Workout, talk to a friend. Accept the fact that some things are out of your control and then let it go. But work on the things that are in your control like smarter eating choices and exercising. Good luck!
