I messed up big time (pls help)

As the title says, I messed up pretty bad. I swapped Ethereum for a coin named Augur and got screwed. It was completely my fault because I wasn’t paying attention. I traded about $27k and only got like $2,800 back. Can there be anything done at all or am I just screwed. This was around 200 days ago, but figured why not ask. Could be in a wallet that u can access or something. All the help would be awesome.
