This question already has an answer here:
Electrum won't let me overwrite the payment with a higher fee either. Any Ideas?
EDIT: I'm using electrum and it wont let me send out another transaction without the "funds" in the wallet which are still unconfirmed. Is there a way to resend the transaction with a higher fee from a website or another wallet? Or is there a way to cancel the entire unconfirmed transaction so I can resend the payment?
Sidenote: There's not enough bitcoin in my wallet to send out a CPFP.
