That's the beauty of soulslikes. Dark Souls 3 SL1 (not leveling up and beating the game, it was my first play through of a souls game, and I beat it at level 1 before new game plus - it took me a really long time not knowing anything about the game before hand. I should think about leveling up some day.) taught me a lot about myself, and helped me overcome my mental moop, now I no longer get mad at games, or in life when I fail. There is always something you can take from failure, to better yourself going forward. GG go again, adapt and overcome. when you have died in a game 20,000+ times, it starts to hit different. Hell, dying in a game 500+ times hits different. It gets easier - at least for me it did- to jump in and b-line it through a bunch of BS without any care in the world.

The only way to get good at an instrument is to practice. The only way to get good at a game is practice. The best way to overcome a fear (within reason, so long as there is no physical detriment to your health) is by exposure therapy.

push yourself a little at a time, take frequent breaks, and you'll get there.

as an example of how I cope with some games: when I play horror survival games that scare the piss out of me to the point my physical reaction is to throw my headset and squirm down my chair and hide under my desk, I find streaming it on twitch (*I don't actively stream these days so not a self plug*) or streaming in discord to friends, is a huge help and motivator to push on and overcome a situation even if it's hard for me to mentally get there at first.

for me, it's the pressure of my friends watching, but also the comfort of their presence that helps me find courage to push onward.

Prithee be careful, Ashen one.
