You're overthinking it. It's one of those annoying internet traits every site, every chat, every comment section has. It gets you at first, later on it's like that meme about listening to your parents tell you about how they had to go to school back in the day. Or an 8th grader telling you as an 7th grader, "just you wait!"
Eventually you'll see it as an everyday thing.
Now lets say it hurt your gaming ego about you being bad or whatever. First time I played Reborn, I was losing to Aya for like 3 hours.
Then there's Rejuvination which I refuse to play unless it's intense mode (see, right there). Narcissa beat my ass so much in my first play that I had to suck it up and look up how others have done it. Then I decided not to take the advice because fucking... why the fuck would I use cheatslikewhathtewwwwwwwwwwwgjk. Trained up new pokemon my way, spent 4 hours more than I should. Is it silly? You tell me.
Cuphead! My favorite example! That blimp fucking boss in the first world made me ragequit. Now I can blitz through the normal mode in like 1 and a half hour. Got all 3 savefiles on 200% and I could do it again twice as fast. In fact, I can probably challenge myself to a deathless run.
I'm not saying don't feel bad. I'm saying get through it. Losing your mind and feeling down over a video game is something we all do. If we're not doing so hot otherwise in life, it feels even worse. But! It's just a part of the process at the time. Useful in the future I might add. Like another level of kaioken.
Cheer up my friend, enjoy the game! Take it as a learning experience! Complaints never beat a single boss. Small breaks for a snack and a song you like might!
