I don't understand what I did wrong
I decided that I am quitting. I just don't think I have what it takes to learn any of this on my own. maybe I am going to use a coach sometime next year and tell him I've never played before, and start from Zero. this is the first time I've ever quitted anything in my life.
I don't really know how anyone does it that doesn't get some sort of guidance from someone. I mean, my dad probably got me to 6-700 uscf, and then a friend and I messed around for a year or so and figured some things out like "rh3 is usually bad" lol. We went to a chess club at 13, when we were like, no idea, but it couldn't have been much more than 1000 uscf. Chess clubs are awesome places where stronger humans can go over the game you lose with you. Helps a ton. My friend is an IM and teaches chess for a living; I never made expert but got to 1913 uscf. But without dad, without the friend, and without the club, I wouldn't have had the ability to do it totally on my own with books and the internet.
2 things..
If you play your kingside pawns like that, your dark squared bishop was very important so play Bg7 and try to hold on to that bishop, trade it off only for something of greater value.
Did you see that your white squared bishop was under attack by that pawn? Back that rook up and move that bishop out of threat. As you saw, the queen pin was not going to last forever.

From move 21 on. You took 1-3 minutes per move. That's not playing daily chess. That' playing speed chess. You're not going to improve playing that way.

Yes slower is better when you are learning. Instead of 29... d2, I think you had promising ideas on the k-side -- f3 with the idea of getting the Q to h3, or h4 to crack open the king. White has Qf7+, so maybe Rg8 first...

Quitting chess seems a bit extreme. The computer actually favored your position by nearly 2 points the move right before you promoted your pawn to a queen. You have to look for the amount of attackers/defenders covering important squares. Yes you promoted your pawn and got a queen but they had both rooks and their queen defending that square so 2 moves later you lost the pawn that was promoted and a rook and your opponent only lost the 1 rook. The pawn attacking your light square bishop was pinned to their queen by your rook. Pushing your C pawn putting extra threat on the b5 square was really your only decent move to make and would have created attacking opportunity for you. Chess is very much live and learn, we all make mistakes. It helps to slow down and think out your moves and the different ways that your opponent has to respond.
