Blunderfest of a game, trying to learn the most from it by posting it here.

I won this game after my opponent accidentally "M1'd" himself, but honestly this was a gigantic blunderfest of the game, and I am trying to make the most of this mess by posting it here for actual human analysis. A little disappointed in myself, since I've been reaching out for help a lot lately to learn and improve.

Anyway, I am ready to be roasted.

It's a definite improvement over the last game you posted.

In any sort of center counter, your usually better off trading pawns and opening the center.

4. ...Bd3 is a bad use of your bishop, relegating it to being more of a pawn than a bishop.

You played the ending quite well. He didn't accidentally lose: black had the advantage. Finding that tactic (2 threats at the same time) is a huge step in understanding and calculation in chess. 

Plus you should never think your opponent accidentally played a less than steller move. Humans are not high level chess engines. GMs use psychology all the time when playing chess: you rattled your opponent's nerves and he got careless.

Remember to go over your games with an engine after you have done this kind of analysis, it will help you improve a lot.  For example, 10. . . . pxp en passant is really strong.  Doing that before you get to us takes care of the simply tactical stuff and allows us to focus more on positional things that the computer isn't great at teaching.
