There is an obvious need to be trusted and open to share knowledge, I don't just want to dump keys and move on, I would like to understand the deeper history, assuming there is or perhaps was one.
If you have a private key to your Bitcoin, you can
import it on electrum wallet.
If you have the wallet file, you can use it if not yet corrupted. Experienced member that run Bitcoin core (I assume you were using Bitcoin qt) will be able to illustrate you how you can recover your private keys from the wallet.dat
Message me if interested.
