So I sent 0.9BTC to an address and for some reason no fees were included.
The transaction has still shown as unconfirmed since 30 hours now so it is unlikely to confirm anytime soon I guess.
I have spoken to a multibit REP and they just said it will be confirmed in time OR will be returned to my wallet which is good news anyway.
Is there anyway to somehow, reset the blockchain on my multibit HD wallet so it can cancel my unconfirmed transaction?
Use "repair wallet"

but as I said I only have to Multibit HD Wallet. I am slightly new to troubleshooting this kind of thing on bitcoins. I have had mediocre experience with it and know nothing about the commands etc.
Thanks
Thats for bitcoin core only. You can also try to spend the change (if any) with a very large fee.
