Bobby Fischer Back Rank Mate

I am a very weak player, only been playing about a year and my rating reflects this:
I just played a game with a player rated 300+ higher than myself and during the mid-game it was apparent I was going to lose (material wise)
Then out of nowhere I spotted an opportunity for a Bobby Fischer back rank mate, and my opponent did not notice it.
Most people on Lichess rated over 1400 would laugh at this, but to me it was a win I should not have achieved and the blunder by my opponent opened up the killing move.
I know I am crap at Chess, but this win has totally made my day!

Hello, nice game, I'm like you, I started chess one years ago, so I will not give you advices, it is better to a more experienced player will give you ...

Play slower, take time to think. At the end you have 7 useless minutes left on your clock.
4 Bc4 loses a pawn. 5 Bd3 insists on losing the pawn, and a piece as well. The game was basically over here.
18 Bf6 loses another piece, which black does not take. And so on and so forth.

Thanks @tpr but I have to disagree somewhat, yes I had '7 useless minutes' left on the clock, but I did win, surely that's the goal of every Chess game? :)
I will certainly take on your advice to 'slow down' though. thanks!
