I think you made too many unnecessary pawn moves in the opening; all of your six first moves are pawn moves that don't develop a single piece. The goad of the opening is not to transform your position into Swiss cheese. White, by contrast, at least developed two pieces.
I think you should look into the Stonewall Dutch (see for example How to Play the Stonewall Dutch) because it uses a pawn structure and plans that you can also use as white, when it is called the Stonewall Attack (see for example The Stonewall Attack — Basic Concepts for Beginners).
However, if you prefer using a king-side fianchetto, check the Leningrad Dutch.
On move 8, I would have played Ng8-f6 (white should then move the bishop back to g2; exchanging it for the knight would create a weakness), followed by king-side castling.
10. ... Nd7-f8 looks strange to me. If the goal was to defend pawn e6 (which was not under attack), Nd7-b6 would have been better, since the bishop then protects the pawn.
11. ... a6 achieves nothing. All your pieces are on the last three rows, where they can't exert any pressure on white's position. It was time to develop pieces, instead of keeping them on the back rows.
13. ... e5 begins to open the centre while the king is still in the middle of the back row. The king should have been moved towards a safe place first, by castling to the king side. (I don't think queen-side castling is often an option in the Dutch Defence. It would have been a bad idea in this game, because the white pawns have already advance to far on that side of the board.)
The white bishop on e4 is difficult to eliminate, and even if you managed to exchange it for your own white-square bishop (a long-winded manoeuvre), it would get replaced by a knight that would be at least as hard to deal with.
29. Nf4 Bxf3+: White blunders a piece by not playing cxd5 (which would, however, create two connected passed pawns), and you just give it back to him by playing Bxf3?!
30. ... Rd8-e8: You probably wanted to take away white's control of the e file, but did you look at playing 30. ... Qc6+ first, so you could prevent the penetration of the white queen into your position via a4?
36. ... g5: Good exploitation of the pin on the knight, which white had clearly overlooked. This is what saves the game for black, especially after the exchange of the queens.
