My MacBook is totally weird. My trackpad is dented in so i cant use it. the keyboard only fully works for passwords and only a couple letters work. WHAT DO I DO!???

Go to an Apple Store and let them check it out. Sounds lie you damaged the unit.

How did the trackpad become dented? And how old is your Macbook and the battery?

Have you looked at your battery? Take a look at it - is it swollen? If it is, stop using it with the battery and replace it immediately before it damages other components.
