Knocked out for the first time

Had my first kickboxing match a few months back. Went out on a limb and decided to fight in a bout because I had always wanted to. Took a fight with this guy in his early 20s who was 1-2. I’m 30.. Dude was over weight by 15 pounds but I still accepted the fight (lesson learned) and instantly I could tell from the first exchanges this guy had all the power on me, I had the speed over him but not the gas tank .. Put up a good fight by throwing a lot of kicks which were doing damage to his legs but he had no respect at all for my punch power. He would swarm me and I’d have to evade.

All those years of sparring I never came close to getting knocked out but after the first knockdown I remember feeling like I could finally relate to all the knockouts I’ve seen on tv/gym etc, and how those guys felt. Was a weird feeling. Couldn’t believe it happened to me.. I was a little rocked but pretty coherent still. Then later on in the first round we were in a good exchange and he snuck a good uppercut that landed flush and I felt my legs give out from under me. I jumped back up to my feet. Then after another knockdown in the second round my corner threw the towel.

Just wanted to ask yall what is the game plan when a guy swarms you with haymakers at will?

And also any stories from the first time you felt what it’s like to be rocked/knocked out?

I lost and struggled with that for a few weeks after, but felt like I gained so much knowledge from that bout. What I need to work on etc.. Plus that experience I’ve never felt more alive in my life. Even though my first fight was a loss I feel I learned so much. Thanks for reading.
