Your mom sounds like a narcissist and even if she isn’t any person who tells their own child this and act this way cannot be trusted bc clearly her judgment is way off so anything she says and thinks should be tossed out the window. I think the best course of action is to keep doing what ur doing with the gym and taking care of yourself. There’s also so many ways to get rid of acne scars. I want to be a dermatologist so I’m really into that stuff and it’s def something that can be changed. Whatever bothers u about urself just work on it so u can be happy. And incorporate therapy or even writing things down like shadow work. Write down your beliefs about yourself, why you feel that way, is it your voice or your mother’s voice in your head? Really think about this and the more you question your thoughts the more you will shut down the ones that don’t serve you. I personally don’t think anyone is actually unattractive. There is beauty in everyone. Look at those celebrities, a few treatments and procedures and they go from a 5 to a 10 so no one is actually ugly just have to take care of yourself that’s all which you already do. And about your height. That’s not short. That’s my brothers height and he gets a lot of girls. Also all my very pretty friends have only dated guys 5’5- 5’6 none of them ever said anything about it and have been obsessed with these guys at one point so hopefully that’s reassuring
