I am 13 years old. My dad is telling me NEVER to resign. I feel like he is taking it to the extreme

My dad not letting me resign at all! I think he is taking it to the extreme for the following reasons:
1. Why do I need to play 25 useless moves before getting checkmated?!
2. Suppose I am in a position where my opponent is cramping me all over the board. Then I will obviously be in pain and have an absolutely lost position. Then I have to play through excruciating pain, and get extremely stressed out. I will harp on it for 2 days and it will be terrible.
My dad makes me resign a correspondence game where I am not in a worse position every time I resign a chess.com game in a losing position. This is obviously too much. I want to know what I can do to deal with my dad’s extreme rules and the pain I am going through because of it.
That's being a jerk.
Quite possibly exaggeration. I agree, that's taking it too far, but you still shouldn't resign.
Why not? It may make sense in blitz or bullet but in correspondence it's preposterous to think they'll blunder bad enough for you to draw or win.

I'm just thinking that if there is "excruciating pain" and stress over a game of chess there are a lot bigger problems in that household than deciding on whether or not to resign that game of chess.
Agreed.

If you want to end your lost game without resigning, just do a King Sacrifice

There are several ways of looking at this:
If you made a silly move and will definitely lose to a respected friend and -YOU ARE PLAYING FOR FUN - resign take the loss and start over another game.
If you will lose , but you want to make it a war of attrition, make your opponent earn the win: earn your loss. Forcing your opponent to beat you means that you both have to work hard. Learning to survive when the odds are against you is a valuable life lesson. You also learn how to maximize the potential of your remaining pieces and pawns. This is especially useful when you are starting out.
If you are playing with your dad and he refuses your resignation, i think that this is what he is trying to teach you.
How long can you last? What are the limitations of the pieces that you have? How can you constrain superior forces with what you have?
If you are getting frustrated ask to play with him : without pieces, without major pieces, knights only, bishops only, rooks only, queens only - keeping the pawns of course. En passant then becomes a valuable offensive tool.
It's as good an exercise as playing or practicing B,B or B,N, or N,N,N vs K.
Play losing End-Game scenarios. B,N,K / B,B K / N,N,N K vs K - beat me , i dare you - then change sides
This teaches you the merits of the individual pieces. This is how i taught my high school club. We were very successful.
It may be more fun this way.
Don't give up.

Resigning the side is part of the game. You are young and learning. You will learn nothing when your opponent is taking excessive pleasure in promoting himself/herself at your expense.
I am a somewhat experienced player and I just moments ago resigned to a lower rated player. He simply played better. Move on.

We learn from our mistakes. (I have learned a lot during my lifetime!!) There are two main reasons to keep playing: 1 to learn from your opponent and 2. your opponent may blunder away a win.
However, there does come a point when continuing on becomes counter productive for both you and your opponent. When that point comes is difficult to say; however, when you think you have reached it, it is time to resign, analyze your game and try to do better next time.
Good luck.

That is ridiculous, first of all why on Earth is he monitoring your chess games online?? 2nd, why does he make you resign games you are winning, what does that have to do with live games? 3rd, he sounds like he has mental problems if he is that OCD about winning chess games. I play for fun here, not for competition purposes whatsoever. I resign if I blunder a piece. I like to continue playing only interesting games.

Also, what is an "engine move" in a completely lost position?
In a KQK endgame, checkmate is guaranteed in 10 moves regardless of whose move it is or the position of the pieces, so it is a waste of time to try and make the "most delaying move", don't worry, anyone over 1000 will NOT fall for stalemate!
