I think you are being too hard on yourself. You didn't gain any weight, you made good or okay choices most of the time and now that you are back home you will continue to make good choices. Imho I think that is what we are all trying to do. If I had made good or okay choices most of the time I wouldn't be 184 lbs but I made more bad choices thus the need for me to diet now. My goal is to be able to eat whatever I want sometimes and eat healthy most of the time and sometimes I am just gonna wanna eat 5 different cookies. Life and food would be pretty boring without good and bad choices.
