Can't improve over 350 ELO.

I know that feeling, but I’ve identified the causes and the likely solutions. I’ve been playing about 2 months now and sitting about mid 300s.

I’m sure many have progressed much faster, but I’m older, and the brute fact is an older brain doesn’t learn as quickly. I suspect most GMs started early in life, but what the hey, I play for enjoyment.

I think for myself and others in similar situations, it’s largely psycho-emotional: frustration, fatigue, lack of patience, lack of sleep, button press errors, etc.

Personally I find the puzzles extremely helpful, and yes, the review engine, which frankly must be taken with a large grain of salt. I don’t take it seriously when it chides me for moving my Queen out of harm’s way because I “missed an opportunity to develop my Bishop”. Other times its advice is obviously sound. 

At some point I’m gonna have to buckle down and learn some theory, but right now I’m having too much fun delivering the occasional checkmate. Ka-pow! 😄

Your chess may be awful (according to your own conclusions) but you do know how to write a humorous and self-deprecating profile text, so kudos to you for that, sir.

he wasn't lying

I'm also 350! i've been doing good but there is always that one streak.... if your going to do a open I suggest "the cow", all of your pieces stay together

Your problem is psychological, not intellectual. Why don’t you go for a run first and play chess afterwords? Or meditate? Anything to get you out of this anxiety and start paying attention. Accept your frustration and stare at the board a little longer. There’s nothing wrong with losing or being low-rated, but it sounds like you could have more fun.

Ah, your message was from way back in 2024. Meanwhile you have improved, congrats!

Honestly it's not much different. I almost reached 1000 elo but lost it all. Everyone from 300-1000 plays the same. I know more stuff, but I'm not better.
