Wallet transfer problem

I have a Blockchain.com wallet account with $100,000 in BTC, I transferred $80,000 BTC to my other wallet, but unfortunately the transaction has been pending, but he has been deducted from the account balance and I see my wallet total is $20,000. One way I see is to create a new wallet and then import mnemonics. My question is: If I create a new wallet and import mnemonics, will I only have $20,000 in my wallet? The other $80,000 is gone forever? So I dare not make this attempt, thank you for your help, it is very important to me!
