it may help to imagine two doors in your mind, one at the front of your head and one at the back. thoughts come in and thoughts go out. then you need to teach yourself not to judge the thoughts in between, just let them pass through. you cant change what happened. tell yourself you are going to make healthier choices in the future if that is helpful. you have thoughts actions and feelings. you thought you were going to get a beer. your actions were too many beers and your feeings about yourself now are negative. you feel bad, guilty. so next time you think about getting a beer what will your positive action be so that you feel good about yourself in the end? you can use this format for any of your life choices. positive thought will lead to a positive action will lead to positive feeling about yourself. good luck.
