Terminating an account to create a new one

I haven’t played on this server (or Terraria at all as a matter of fact) for years. I’m looking to come back the game and the server for a fresh start. I’m having trouble registering a new character (under a different name) and I kind of want to get away from this pile of cringe that I once called an account. Is there any this account can be terminated so I can start again? Thanks in advance.
