I put my old Gmail accounts on websites like haveibeenpwned.com osintleak.com pentester.com and osint.industries

And the results had a lot of personal info like old usernames I used, old passwords, IP addresses and other info

What can I do now?

I deleted all of my old Gmail accounts. I changed all of my usernames everywhere or deleted the accounts associated with them and changed all the passwords. I use Proton and Email aliases when signing up for services and random generated passwords with fake info everywhere(if possible) and I do use a VPN on all of my devices.

Is there anything more I can do?

Because those Emails had my full real name in them and I used them literally everywhere.
