When was the move of no return?

Hello chess fanatics! I am sharing this game with you because I know that most of you are both much smarter and better at chess than me and I'm curious as to when black lost this game. Please realize that I am a complete amateur who loves to play daring and unsound moves because I find it exciting! I played this game as white on an app called "chess with friends" so I just replicated it on here. I will post the full game below what I think is the fun part, but please don't be shocked when you see how badly we play! Any advice or options are more than welcome. Thank you! 

And here's the full game :)
