Counting lakota

I don't FUCKING UNDERSTAND how to beat Lakota. They mas cav so GODDAMN fast and just run me over. They make axe riders I make sepoy, they still win. They make bowriders and rifle riders I make gurka and sepoy, they still win. I destroy his entire base and town center at 10 minutes in the game, he rebuilds in the blink of an eye and never stops FUCKING raiding me and I STILL lose. I try and build walls but he masses too fucking quickly and if he doesn't he just goes to age 3 and gives all his units tons of siege so I STILL lose

NOTHING FUCKING WORKS AND IT PISSES ME OFF

I have played this game for YEARS and I am very competent, and yet in all the years I've played, I can count the number of victories I've had against lakota on one hand

What am I doing wrong?!?!
