I tried to send an Ethereum transaction using https://www.myetherwallet.com/ over 40 days ago. I used a very low fee and seems it was not nearly enough. The transaction is now stuck and says pending. It doesnt look like it will be dropped and I am not sure what to do.

I tried to speed it up by adding more gas through Metamask but every time I do that I get an error in MEW and it fails. I read somewhere that I need to spend the same nonce with more gas for the transaction to be confirmed. I have no idea how to do that. Can someone help?

Has anyone faced similar issues wit stuck Eth transactions that couldnt be spent and how do I solve this? 
What is going on with the fees and why is an ETH transaction more expensive than a Bitcoin transaction?
