First of all welcome to bitcoin.
I think it is great that you are trying it out and that you have chosen Electrum. :-)

At the moment the blocks are full and thus transactions with higher fees get prioritized.
Because your fee is low chances are slim that it will be included in a block any time soon if at all.

But rest assure that the bitcoins are not gone.
Should the transaction not confirm within a few days the transaction will be removed from the mempool (where all the not included transaction wait to be included).
Should this happen then the bitcoins will be spendable again from their original addresses.

If you have any more question please don't hesitate to ask them.
Bitcoin is great once you start to understand how it works.
