Hey guys, I hope you can help me, let me describe the situation. This is my wallet on Forkdelta

http://blob:https://www.reddit.com/b1f44341-8c7e-4f0c-8ce2-bcf0d8fb0aa1

I made a withdrawal request for 0.251 Maybe that was the mistake, since I didn't realize this was a round up (actually have 0.2509... in the wallet as per picture)

The withdrawal has been pending for hours (here is the transaction https://etherscan.io/tx/0x5d813917bb10613c6f212bf32b5eed46302a6611b17464118c5d14aa4afad4ad)

Through metamask I have tried speeding up or canceling the transaction several times, but nothing happens! In the meantime I even went I did a second withdrawal of 0.23 just to make sure it would be enough, hoping it would somehow cancel the other. Obviously didn't, now that second one is there waiting for the first one to finalize/cancel.
Any idea what I can do?
