How can those close to me support me in my weight loss journey?

Talk about your goal. Let your family know what you are working on and give them ideas how they can help. Clearly defining your goal - will help both you and people you want help from.
Tell them. If your friends know that you are trying to lose weight, they can support you by not tempting you with snacks and high calorie treats, and helping you feel loved and accepted. Calling a friend can help when you feel like you have to eat.
