Just stalked myself and extremely paranoid about being exposed because some things i am unable to remove from the internet

I started chatting on multiple forums, so i decided to try and completely erase my existence from the internet history as much as i can, and while i was somewhat successful, i can still see my old linkedin full name with my country upon searching with site:linkedin.com name country interest another interest

And i found a couple of my old reddit account that i deactivated upon digging a bit online and sadly both of them have the same alias or part of the alias in them, pretty identifiable if someone really wanted to find me, and that could lead to other websites that i used in the past, which can lead to them knowing the people i talk to or the people in my circle, or my college, and somehow find out a scandal of some sort about me and decide to dox and ruin my life.

I am very scared and extremely paranoid and i don’t know what to do with this nagging thought in my head that they will look me up and find me through these simple clues, which are the site:LinkedIn.com or site:reddit.com - those are pretty much all of my concerns

I have placed a vpn in place, bitwarden, ublock, i use brave, i unlinked my emails from any unnecessary application, i erased all my accounts on any type of social media, i removed all my pictures from everywhere, i used different usernames jn every site, i am in the process of dedicating very strong different passwords for each of my emails and each of everything i browse.

Please help and provide your insight on how i might be able to remove this data from the search results
