I have two unconfirmed transactions, one from one year ago and another from about 16 months ago. I am not sure if they are gone for good or if I can try something like a 2x transaction etc. I'm running bitcoin core, latest rev on a mac. I don't have enough in my wallet to even cover a double transaction. Any viable advice would be appreciated.
edit: it appears when I tried to send two separate transactions at the time, I never sent enough for the transaction fees.
