Mods, please help !

Hello-
I would like to go back to my original account and need help. Somehow I wrote my password down wrong or messed it up bc I apparently have it wrong and I have had my account so long, I don’t recall my old email I used. Because of that, I can reset my password. Is there any way I can go back to my original account? My handle is/was: hdgymrat

I had to create this to get back in, but I would like my original. Help if possible please.
Thank you all in advance!

If you didn’t know the email how do you know the password is wrong??

working on it
