Learning to overcome emotional eating is not an easy thing. Emotional eating is a complex issue with no easy solution. It really does take time to change habits.
I give all new Spark members one piece of advice when they start out,"Don't look at good health or weight loss with an all or nothing mentality". If the only healthy thing you did for yourself was to drink 8 glasses of water, that's still a step in the right direction. And that's what Spark is all about. It's all about taking small steps towards your goals. Don't try to do everything at once or you will end up frustrated. No one ever became a healthy eater overnight. it's impossible.
That's why you need to cut yourself some slack. You're not perfect. You're doing to make mistakes. We all did. It's part of the learning process. Where to start ? Start by reading some of the great spark articles on emotional eating. The more you learn the better you'll be able to cope with your stress in ways that don't involve food. You really don't need food to feel better. www.sparkpeople.com/resource/wellness_arti
Be kind to yourself as you would to others.
