Oh I feel your pain. Do you remember what community you used to create your Hive account, like Splinterlands, Ecency, PeadkD? They might be able to help you on Discord.

Let me know if you need invites to any Discord channels, but I am sure you can find them on the main pages for the community you joined Hive with
