Hi guys!

So I sent a transaction last night before my wallet fully synced.

Turns out after examination of the explorer for my wallet address that it was for more than I had available (but the amount that showed in the wallet at the time) so now seems to be stuck in limbo with no confirmations. Is there anything I can do to reverse this transaction and start again? If anyone can help at all that would be amazing!!

The TX id is: ffdcb7d827149ea2ce6b5939709312ce9c2d9d527f4e91c980675e6af75153a2-000
The receiving wallet is: MMzzEE4E81aydiWZkZ7JYDRjuQx7BSwFs9
The sending wallet is: MKYwj7LzzEtRx3VFRzB4aHFhbKPUfm2ZKu

I am on a Mac.

Thanks!
