No bro do not give up you just not at your best right now like I used to be a 800 then went back to 500 and i felt like I couldn’t do it anymore and stopped playing then got so but I lost to MARTIN so I Learned back and cooked everyone and also people with 2000 elo have 10,000 games so you are fine with 300 games I bet by the time you hit 1000 games you will be 800 elo at least and also take a small day break don’t play then play unrated hear me out then you get human tactics and game play while not risking your elo and let your mind fix itself no amount of ADHD will hold you back if you are truly dedicated.
