Self confidence

I am still in my teenage years. And I’ve always struggled to fell happy with myself and be happy with my body. But recently it’s been a lot worse with quarantine and having to be close to my mom 24/7. I hate it. She’s always putting me down and telling me that all I do is eat and stay fat. Every time I go to the kitchen to have a simple snack she judges me and gives me a horrible look as if I was just getting fatter by the minute. I work out constantly and for the first time in years have I seen my body change to the way I always wanted it to be. But still, my mom everyday finds a way to call me fat or judge me. I always just pretend it doesn’t hurt me and I used to be able to tune her out. But I just can’t anymore, I hear every mumble she says about my body, I see every look. And when I try to tell her it hurts me she just says I’m being exaggerated and it’s not true. I hate it so much. I try not to cry cause she’ll judge me for that too and I really just don’t know what to do. It’s like she’s always in a bad mood and she likes to put me down.
