I hear ya man, I have lost many nights of sleep after losing a game by some fluke etc, still to this day it isn't easy to just forget a bad loss, even though it's the best thing to do, but we are only human. GL the rest of the way. Btw, do you play any other sports?
I do football as well (Everything, not just over/unders lol), but I'd be lying if I said I was as good in any other sport as I am with baseball. I mean, I'm pretty good with football, but baseball is my absolutely peak, period.
Then again, having that mindset where I don't put pressure on myself, which is what I was doing a lot of with baseball throughout the first-half of the season, could do wonders for me in other sports so we'll see. With baseball, I'm a perfectionist because I feel I know more about starting pitchers than anyone out there, including a lot of people who even work in baseball. With other sports, I'm absolutely knowledgable as well, but not all over everything like I am with baseball, so having that freedom where I don't expect to win every time, and thus not get upset and devestated when I don't, is exactly an attitude that could lead to winning. Like I said, it's all mental
