Old habit popped up

The 13th was a strange day. I spent most of the day feeling so full the thought of food made me hurt. I was having a hrad time with even drinking. I did stick to the diet plan all day. The irony to this is that we went to my sister-in-laws house for her birthday. The ususal suspects were there, and I was apprehensive about going. I knew the liquer was flowing and that ment someone would have an attitude or behavior issue. I have worked so hard at distancing myself from that and setting a good example to my children. Well, last night my husband and I with my parent-in-laws arrived late and into a war zone of anger and bad behaivor. windows were broken (this is at an apartment) and yelling and screaming was everywhere. My sister-in0law (BIRTHDAY GIRL) was crying. I couldn't get her to calm down and my husband couldn't get his brother to calm down. my mother-in-law is hysterical because she is afraid of someone  getting carted off to jail. pure chaos.  to make a long story short after my husband and I went home I wanted to eat. I did realize that I needed a protein shake , so I tried to curb my food and frustration. It worked for a while. But before I went to bed I splurged and ate 2 oz of sliced cheese. I know it sounds crazy, but lets get real....Was I hungry. No wince I had been having issues of fullness all day. I ate because I was trying to dissipate my anxiety about all the drama. I have reasoned with myself that I spurged on protein and only ate 2 ounces but I ended up with discomfort in my stomach. I am disappointed in my weakness and slipping into comfort  and old habit.
