I checked out the previous threads you posted, and noticed that most of them are about strategy. This is really good, but it also means that your tactical skills are improving while your mental game lags behind. So when things are going good for you, you're on top of the world. But when you get sucked out on, you feel upset because of the disparity between your mental A game and your mental C game.
You also mention that you don't tilt, but your entire post is about you being angry. That's tilt. Tilts impossible to fix if you can't even acknowledge that you do it in the first place. Also, I notice in the
"out of sync" thread you ask a question and proceed to berate the answers you didn't like. Including from some of the respected posters on there. The same in this thread, where you rip on all the comments you don't like.
I've done the same in the past under a different username, and anytime I go back and read my replies, it's no wonder I wasn't improving and people hardly replied to my threads. Just something to consider.
