Weight and healthy junk..

So earlier this year i decided to cut out soda and join a gym..well actually i was doing really good for a while and was down to mabye on soda a day and drinking vitamin water, going to the gym..But then my membership was up for the trial days and we didnt have the money to get me a full one. so i stopped going. Then i was bored and thirsty and no water around. But there was mountain dew.. my soda of choice so i gave in and is pretty much drinking it regularly now. I feel really guilty when i think about it and im sure i have regained some weight. but either way i seem to always feels bad about the way my body looks. So i wear baggier shirts and 2 pairs of pants. Even when i lost a couple pounds here and there. So yeah..i have issues with my weight and such and me being really lazy and bored most of the time doesnt help..But it could just be my anxiety..
