I really need help

14.Posting again.I fucking hate myself.I truly believe I've developed an addiction to sugar.Im fat as fuck,72kg at 167 cm.Ive got some muscle because I used to go to the gym but I stopped.I tried to stop for one day and I just fucking couldn't.i went the whole day not eating anything with sugar but stopped at a shop to get some water.Bought a pack of skittles and a chocolate bar too.I swore I'd leave them for tommorow.Ate them all in one night.Please.My biggest fear is looking obese.Ive been having shitty thoughts and I don't know what to do.
