How to Recover Missing Characters and Lost Brawl Stars Accounts?

I've been playing Brawl Stars for quite a while now, but lately, I've been encountering some rather troubling problems. I've run out of gems, and it's quite disheartening. I'm feeling really disappointed because the characters I was hoping for aren't showing up, and it's really crushing my dreams. I absolutely adore Crown, and I really, really want it. I fantasize about acquiring 2,500 gems, but it seems like an unattainable goal, which leaves me feeling utterly crushed. My initial account was taken from me, which had a profound impact on my emotions, and I still experience a sense of sadness when I reflect on it. I had a character on my old account that I absolutely adored, named Crown.
