You haven't lost your Bitcoins. Right now the bitcoin fee rate is very high for quicker confirmations (over 90 sats/vbyte), and you did send out your transaction at only 27 sats/vbyte. Your transaction is low priority, so miners won't pick it up to be included in the next Bitcoin block to be confirmed and will probably be dropped out of the mempool after approximately 2 weeks from the date the transaction was created if the bitcoin transaction fee rate remains high. You will be able to see your unspent Bitcoins in your wallet at that time and be able to resend at a higher fee rate.

What type of wallet were you sending the coins from?
