My Mac Is Broken

I have a 2020 M1 MacBook. However, the screen is damaged from being hit by a water bottle.

I actually don’t really need this MacBook but it’s comfortable to me. I use it for watching movies and doing light tasks like code or reading. It's portable and lightweight and fit well to my daily bag.

What do you think I should do? I'm confused about whether to repair this MacBook. The screen repair cost around $240, while the second-hand value of this laptop is around $500. What’s the best thing i can do about this?
