@oikonomia I have admittedly never been a black girl, but with life experience I can say that if you are living your own authentic values, then feeling bad about yourself will reduce over time.
You say you’re 20 and that has a lot to do with it. There’s a strong desire to live the
right way and therefore a strong desire to match templates and live the way “a person” is supposed to live. At the same time, as you enter adulthood, you’re facing the practical reality that you can’t be or do everything.
So you can’t be a fitness girl
and a thicc/partying/drinking girl, and you know this and are happy with your choice, but the reality of not being able to match both lifestyles at once brings anxious feelings. As you get older your feelings will align with the facts more and more.
Maybe you’re also worried about losing friends, which can come with a lifestyle change. But if you pull your weight in the friendship then true friends will still be true friends, only superficial friendships will fall away. Plus some of your friends will start to think your lifestyle is preferable to a hangover, and join you.
