First, calm down and check the circle icon on the lower-right, if it is red or circulating arrows, your client is just disconnected to a server or if it's newly installed, it is still downloading the "
block_headers".
Now, please tell us the version number of your Electrum (
Latest is v3.3.5), where did you downloaded it and if you don't mind (
no if privacy matters) the receiver's bitcoin address.
The bitcoins aren't stored in the wallet, it's in the network. As long as you have the receiver's Electrum's SEED (
12 random-words), those bitcoins are still in your control
