My account got hacked

My account got hacked 

by downloading a goddamn “test my game” thingy, whenever I try to change my pass it kept saying my email does not exist. Now I made a new account with the same gmail and it made a new account, now im worried they changed my entire Gmail and pass from my ORIGINAL account, the ticket i sent discord was just dead quiet, a few bot replies here and there and they didnt help at all, infact they made my issue named ‘solved’ its been already 6 days and im getting a worried ill never get my account back, i have so much memories there and i had that account for 7 years.
