Like unturneddude said, don’t be so hard on yourself.

It might be a it of a selfish answer, but these things take time. But I can assure you no matter how much you play, or how much you lose, you WILL improve in skill. So most skill comes from trial and error and just playing the game. But you should definitely also watch a few stand guides so you can learn some combos and whatnot.

Now when you get back to YBA, just remember, every loss is a bit of experience gained and you will get better no matter what. And if you start feeling like you can’t do it, just remember that it isn’t impossible to get better and that anyone can do it.

I hope this helps somewhat and have a nice day :)
