Need pros with a bit of time

I was wondering if I could play someone an have you tell me what I consistently am doing wrong in your spare time-you could practice different traps opening ect.

I have been playing chess since third grade, a year ago I got back into it I ya almost day on the app. I read an entire book on it I think it's called The Chess Bible, watched so many vids on youtube. I spend so much time I want to know how I could get better: I fluctuate between 800 lowest and 1300 highest, depending on what drug I have taken lol, but nah most of the time I'm not playing high, it's just that I seem to fall back into the 800-900 range then, and I can't accept that drugs make me better, so I must just be over analyzing. But I'm talking about standard or ten minute, I tend to do better the lower the timer is, but it's not as tactical and strategic then to me, it's just about who can analyze quicker

Anyways, in my opinion memorization is not the best way to learn; so if someone could point out common mistakes, I assume I will correct them and become a better player quicker than repetitively playing endless games. Thank ya

you  could try using a chess engine to analyse your games to see where you
went wrong.
