Seperated My Shoulder

A few months i separated my shoulder in football, kept playing with it cause im a fucking idiot, doctor said i was separated but i can still workout, but not go down all the way when benching. So being 16 years old i ignored him and went all the way down to the chest when i was benching, i can feel it pulling on my deltoid on the way down, anyways anyone have this problem with a separated shoulder? thanks!

what can i do to recover from this injury for next season?
