I'm heartbrokren and frustrated not knowing what happend , I was always prepared to lose crypto even I I fully believed in it but not like this. I'm usually the guy that tells others to be paranoid about security.
I get the feeling you're a bit muddled on how Bitcoin wallets actually work. You're mixing up terms and saying things that don't make much sense. All wallets nowadays generate multiple public addresses spawned from one original seed and this covers change addresses too. So there's no master address or single address that represents your entire wallet. Unless you imported the wallet using a private key - that wallet would have only one public address (well actually three, depending on the script type, but I won't get into that).
I strongly recommend you ask someone with more expertise for assistance if you dont wanna risk losing your money forever with amateur moves.
