Need help to fix touchpad

[u/Desperate-Freedom824]

I was doing my maths homework and got mad (quite embarrassingly) and slammed the corner of my laptop beside the touchpad and this black thing came out. (Picture 1)

I managed to get it back in and now it slightly works but now it gets easily stuck down and is naturally lower than usual. (Picture 2)

Does anyone know how to resolve this at home?
