Account deletion

Hello, everyone.
I just wanna ask how to delete wordpress account that was made 10 years ago.? I already forgot the password, and the wordpress was only made because it was a requirement when I was in Highschool for us to graduate, never thought to delete it after. Now, every time that I will search my whole name, that wordpress will come out, and all the poems and stories I made, and pictures I uploaded were still up. Some pictures that posted were already a memories that are shameful to share nowadays, hahaha..

so i badly wants to delete it..

PS. tried to open my account using my (insert name) wordpress . com and clicked the "forgot password" but it says there that the account has been deleted something like that. But then, my account still pops out everytime I searched it..

please send Help 🙏🏻🙏🏻 Thank youuu🥹
