I suggest you retrieve the private key from your core wallet and use another wallet instead like an Electrum wallet. Just do this if you still stuck from suggested above.
If you can't wait for a syncing dump the private key from bitcoin core wallet.
- Follow this guide below.
- Click the help button from menu bar at the top right.
- Find the debug window
- Then Select the console tab
- If your wallet has wallet passphrase or password you need to enter this
walletpassphrase mypassword 600
- Then submit this
dumpprivkey [mybitcoin address]
Once you have the private key you can now install Electrum wallet and use the private key to restore it to the Electrum wallet. After you restore you can start sending your bitcoin again to other bitcoin addresses without waiting for syncing.
