So here I am with 8 blocks since my fail and 0 confirmations on anything. I've never done this before and would really like to know, while I am sure it is unknown, how long my coin could be possibly lost in space.
First thing I would do is to know whether those transactions appear on the mempool. Use these blockexplorers to view your addresses and transactions ids:
https://blockchain.infohttps://btc.blockr.ioIf you can see your problematic transactions on the blockexplorers, you need to wait for them to confirm or disappear. If they are not there, backup your wallet file and restore your electrum wallet from seed and create the transactions again.
Your wallet is called "default_wallet", should be found here:
\Users\YourUserName\AppData\Roaming\Local\Electrum\Wallet
You can view your wallet seed by clicking:
Menu | Wallet | Seed (then enter your password)
If you restore from seed, you will loose all the keys for those addresses not generated by Electrum: Those extra private keys you imported yourself. So backup your wallet!
