It looks like you had a tough time against some more experienced yet unpleasant opponents, and on top of that made a few mistakes while flying a difficult list. Carnor Jax is probably the single most difficult ship to keep alive while using his ability, but when you manage it he ruins x7 defenders. I've yet to try the strikers (they haven't been released where I am) but I doubt that they're easy to fly with the title. If I were you I would simply keep practicing on Vassal and/or on casual game nights, and keep my chin up because, like others have said, we've all been curb-stomped before. And don't forget that the vast majority of the X-Wing community is made up of generally nice people, so hopefully your unpleasant opponents that day were just outliers and most of your community is more fun to play against.
In my area I kind of have a reputation for being a difficult opponent to beat and whenever I'm facing a new player they tend to already know who I am and often start the game telling me that they're new and that they're going to lose. In these cases I feel like an ambassador to the game (so no trash talk like I do with my friends) and generally reply that you can never know the result before playing. Sometimes the matches are much closer than expected because they're super-concentrated on not making mistakes and end up doing everything right, and sometimes they're a walk through the park, but after the match I always try to start a polite discussion on where the match was decided, which maneuvers may have been better and generally try to improve their game. If we both walk away with a smile despite the result then all the better, because all we really want by playing is to spend a few hours going pew pew pew with plastic space ships.
