I made a transactions over 48 hours ago and it is unconfirmed. I have been buying BTC since early 2011 at $7.
I've never had an issue with unconfirmed transactions and, I'm not sure what to do. I used Electrum to send my coin as I have many times.
I see that I messed up and sent all my BTC which left a tiny fee. I'm not sure how to backup Electrum and pseudo double spend my coin.
Can anyone with experience help me cancel this transaction?

most probably his wallet is not synced with the network yet.
To OP: let the wallet (Electrum) be open for a while so that it can sync. you can also change your server that you are connected to if you have trouble with the current one.
go to Tools > Network
and it should say 452203 as your block height, if not you can change the server to something else manually (such as ecdsa.org) and wait for it to download the blockchain headers.
