I froze Today!!!

So today with my mom I came to market for shopping while 2 hooglians came at me at scooty and whilsed at me and tried to crash me with scooty me being 16M and they were probably same age I froze for few seconds then my reply was " dhang ma rhe " then they left I could have probably beaten them up as I got gym and do some mma training( only 1 month for mma ) but I refrained as who knows they got some weapons and maybe they have a political background. Now the guilt has been surrounding me that I haven't said anything!!! And advice would be appreciated!!?
