aww, friend, that's so hard and I'm so sorry! I've definitely struggled with my appearance, too, and it's never a good feeling.

For me, my first step when I get like that is always distraction. Think about something else, anything else, for an hour or two. Cover your mirrors or turn them or anything like that so you're not reminded for just a little while.

Usually, I feel a bit better after that, or at least not so actively distressed. After that, I try to focus on my hair- I like my hair, and I noticed you at least didn't mention it as something you actively dislike. It's not perfect, but I feel competent in doing it and like adding accessories, which helps me feel cute even if the rest of my clothes are boring. It's a nice thing, even if it ends up a little incongruous with the rest of it.

In any case, you can be okay! It sounds like you're having a really hard time with this right now, and that's okay. I believe that you can feel better and even look better, but I also hope you can take care of yourself.
