I need help regarding my wallet adress

I received a wallet address when I was creating my account and sent a transfer from Coinbase now I can`t find this wallet address but am showing a different address in my Bisq wallet…whats up and can I use this original Address for my Address now??

The address I sent to was provided to me by this site…is my money gone for good?

I am not sure I understand your situation. You had an address on Coinbase with bitcoins in it and then sent it to another address, right? That address where you sent the bitcoins, where did you create it? In Bisq app?
