What is my crime?

Sir, on Saturday evening, I and my friend had a drink and went to eat something at city centre. Suddenly an SBI armoured car came from a wrong side and was giving horns, so I told them not to do so, and the driver was angry on me and all of a sudden he and the other two with him the security guard and other man started assaulting me infront of a public, though I didn't used any slang words. Later on spot police came and I told them I'm going to police station for an FIR. I went there but couldn't do FIR and the cops took us to the hospital for medical test, at the hospital the doctor didn't do anything he just signed the papers and the cops took us to the station, later we came out on bail that night. On Sunday evening I went to police station for informing them that I don't want to waste my time on police case so I want to compromise with those three person who've assaulted me, specially the security guard assaulted on my head with his weapon. What steps can I take? For the reason I was drunk and for the case? please advice me, I'm depressed as my examination is starting from 13th Dec.
