Bad Play or Bad Beat?

Im new here and I was just wondering whether I did something wrong on this hand or if it was just a bad beat. Any feedback is welcome.

Bad beat, u got all the chips in when he was behind.

is this play money or tourney or something?

and if his raise wasn't so obnoxiously big then he'd probably have you beat.

post in correct forum and no you didn't do anything wrong.
