Unity 2D - Need Help Staying Crouched while Under Something

Howdy!

So my question is simple; I'm building a 2D platformer and I'm trying to simply implement some functionality that will help players have a better game feel, and possibly prevent bugs. All I'd like to do is to check if something is above my character and keep him crouching if I'm underneath something. The moment I come out from under said thing, I'd like to stand back up (if not holding crouch).

Normally, I have players hold Left Control to crouch, and the character stands when it's released. I'd like to know how to keep the character crouched if under something, and especially if under something with the button released. Then simply spring upward when out from under said thing.

Any help is appreciated and I'll include my character controller for reference. Oh, and I guess it'd also be helpful to mention that I'm using Unity 2019.1.4f1. If I need to upgrade, I can; just thought I'd clarify.

Thanks guys!

When going under, it will remain crouched (which is good) // however, once you need to "stand" the animation never happens. /*bool Stand() { //work in progress }*/ }
