Don't get discouraged Eagle! I basically say what you are saying after every tournament I feel I do bad at. It's extremely tough and annoying to feel like you are not performing/succeeding at the level you think you should, I get that. It can be hard to care so much about the game and at the same time not let the losses get to you like that. Take a break if you need to if the losses affect you like that every time, a break can actually be very good for you. But don't say that you are done, that's just silly. Also don't hold out hope for smash 4, every character will have a grab release on Ness and there will be air tripping.
I was losing friendlies even worse than I was losing tourney matches. Friendlies are meant for fun, but when you're trying to have fun and all you're getting is BS, it's difficult to still want to play. I had little to no fun at that tournament and now I'm out like $70 for the whole trip. Probably a bad idea going to an OoS tournament, probably also losing a bunch due to the fact that the tournament was "stacked" according to everyone else, but I shouldn't have gotten annihilated the way I did.
I normally have perfect control over Ness' aerials and platform maneuvering, and I like when I can go across the stage and kill someone by my awesome reads and movement and aerial placement... When I input rolls or something instead of what I meant to do, it's not really fun, it's just frustrating.
I guess it'd be good to take a break, but I don't know if I'd WANT to come back to the game. I've started hating every video game that I play. I used to love playing TF2, but now I'm just bored within a couple minutes of playing it. I used to love playing a bunch of FPS games and fighters, but they don't entertain me. I find much more enjoyment in just hanging out with all my friends, watching movies, playing non-video games, and going on hilarious treks everywhere.
I've also got school. I was looking into smash things enough to the point where I would distract myself from homework at the worst times. I can't afford to put time into the game because I need to do well in college. If I don't, it'll suck for a long time and my family will be disappointed in me, because my parents essentially expect perfect grades and everything from me, seeing as my older brother got basically perfect grades in college and I'm SUPPOSED to be smarter than him... I guess I am, but I'm not dedicated enough (I'll go to class, listen, and retain info to an insane amount without even reviewing information that heavily, then go to take an exam and get high grades... minus this last ECE exam, but I wasn't paying attention in lecture and skipped a bunch)
I DIGRESS! I used to love playing all these games, but the only reason that I've kept playing brawl is because I enjoy playing Ness... WELL! The modifier is WELL. I don't care if I lose to a good player legitimately by them outplaying me (that happened last tournament when I lost to Cheese and Legan), but when I lose because of the fact that I make thousands of mistakes in one day, it makes me not want to play. If I'm not doing well, I'm essentially not having fun. I can do well and lose and have loads of fun, but I don't enjoy doing terribly.
I'll probably just find some way of showing all you Ness mains some of my tricks and then just quit. Either that or I'll come back sometime next year after APEX. I'll decide then whether or not I feel like coming back, but I'm taking a long hiatus after SHOWING YOU MAH MOVES!
