For fast confirmations you need to pay a rate of 360 satoshis/byte today according to https://bitcoinfees.21.co/
To prevent it happening again first make sure you are using the latest version of electrum. Afterwards click tools in your electrum wallet's menu bar, then click preferences, then click the fees tab. Check the box marked "use dynamic fees".
To speed up your current transaction's confirmation time you can try using this free service at the start of each hour.
I faced a similar issue a few days back transaction not getting confirmed due to low fee but user "QuickSeller" got my transaction confirmed in minutes when I sent him 0.0001 BTC. He has access to some pool . PM him.
If you choose to do nothing your transaction will either eventually confirm, or the network will forget about it and your Bitcoins will return yo your wallet.
