Today I deactivated the @stekosteko account at Twitter. It had been inactive for four years, but deleting it right now is a good thing to do. I have an archive of all my tweets, someday I will publish it but I doubt there is anything that important in it. I was very active on Twitter at some point, and I even identified with that username – call me lucky for escaping that alternate reality soon enough.
I encourage you to delete your own account and find your way in the Fediverse. I’m at https://octodon.social/@steko
