If you answered yes to that question, there are several things you can do to help yourself.
1. Look at why you are. Figure out the root of the issue/s. That can be a difficult thing to do. You are the only one that can change. Don't expect change from other people. Once you find the issue/s, then you can begin to make the necessary changes. This won't happen overnight however, it will take time.
2. Find something you enjoy that will keep your mind off of food, exercise, meditate or even a hobby.
3. Get plenty of sleep and rejuvenate your body. Unwind. Finding other ways to cope it the best idea.
4. Drink plenty of water. When you drink water, you find that you don't need to eat as much.
Remember: You are doing this for you, no one else to become healthier and happier.
