i can't think

i am playing horribly. i literally can't seem to think about what my opponent is playing. i feel like i have got myself into a habit of playing the first move that comes to mind, or calculating a few moves and then playing the second move that comes to mind. why? is it because I am sleepy, or perhaps i played too much blitz?

I tilted a bit in blitz today feeling like that, which is why I play my best chess in the morning, when I'm fresh. Don't play when you're tired.

but i have school in the morning and whenever i play chess i end up extending it and i don't have time to do other stuff

Instead of changing my time, is there a way to make the time which I already spend on chess useful?

sometimes when I'm frustrated I'll resign equal positions that I find boring. So you not alone in your struggles, my rapid rating has capitulated recently

Check my game today. Also, I keep on having to reload the puzzles page because I can't solve any of them. I only have gotten 2 puzzles done today. I played a game against the computer and I blundered the exchange due to a simple move.

The exact same thing happened with me a few days ago. Well, then I switched to rapid and tried to work on my chess, (I wasn’t able to do that coz I became lazy due to Blitz), but leaving Blitz completely and switching to rapid was actually very good for me, I reached 1900 a few days ago. 

A little more than a bit*

Don't try

Bit more that it

I get what you mean. Happens to me sometimes.

But, for some reason it can help me as well. Like, one time I was feeling numb and was playing for way too long, but then went 30 points over my peak.

Bro I shouldn't even play chess.

I play chess when I'm tired, resulting to bunch of blunders so I find my way to do it when I'm refreshed, but It just got worse. My brain cell is lower than my elo
