I need to vent and I need advice

Okay. So don't worry this won't be long. I currently have these issues

- I have scars all over my thighs and I feel so insecure about them. Everyone's wearing rompers and shorts and I can't. It makes me feel ugly and stupid. How do I get them to fade?

- I'm constantly very anxious and I can't sit still in one place. I drive myself crazy by being paranoid and overthinking and this leads to me staying up and getting little to no sleep.

- I have school tomorrow and it honestly makes my anxiety worse and makes me insecure.

I feel like a mess. Help?
