Italian nightmare

this was an OTB game, not a top game, but it doesn't happen so often that my Italian games can be so scary early on, besides some quick trap wins. The problem here with black was it played to long pawns, while white developed, offered, and attacked. At some points, it was not my best move either (i could have loosened my queen as well here) but chess is a bit of a psychological game too. (look for example that early knight exchange, my only goal was to get rid of his only active major peace, and it worked cause I played quickly. Oh well here is the game, black resigned in the end.
