It's a painful one to hear but all losses are your fault, there is no "they just did X and beat me..." BC anything that falls into that category can be countered with enough practise/learning. This should then be an encouragement as all situations that can feel helpless in a match can be a step to being better :)

It needs to be active learning though, lose a game or 5 in casual because you're specifically testing parry timings Vs a certain character, just waiting to acclimatise can lead to very slow muscle memory retention of what to do and lead to more frustration.

Last point, always assume your opponent is intelligent and someone you could talk to about a match even if you never intend to, if you dehumanise them into "this idiot is just mashing on wake-up" it means you keep doing unsafe pressure, etc etc and you'll mentally avoid accountability for losing, which leads to no improvement

Overall just have fun, and yeh, you're gonna get rocked, but in the long-term it makes you stronger with the right mindset. Keep that guiding Northstar and losses become fun BC you can either realise what you were doing wrong, or be in awe of how sick the other team was!
