21st Birthday

Hello! Next Thursday is my 21st birthday, and I want to drink/not worry about calories. However, today was my little sister’s birthday and I splurged on cake + dinner. Too much. Wayyy too much. I’ve only been on my deficit for a week and a half. 😭 So I haven’t lost any weight except for maybe a pound lol. That pound and more will likely be gained if I let loose on my birthday. That being the case, I’m thinking why even continue with the calorie deficit next week if I’m going to have to restart after my birthday? Am I being stupid?😣
