Unlike reddit, you can bring most of your account with you to a new instance (a different server. basically imagine each instance is its own mini-reddit, and all the mini-reddits can talk to each other).
If you go to your Account Settings page, you can export your account JSON file, which you can then import into a new instance so you can bring your subscriptions, blocks, and favorited comments/posts.
To help choose a new instance, check out this comment.
I know, I'm the one who approved your application.
You happened to sign up right before we've had our first particularly bad issue in 3 years. Unlucky, yes, but it's a bit out of order (IMO) to say we're a poorly managed instance based on that, especially seeing as you lost nothing besides the time it took to write your application. :\
