Indeed.
Now what's the solution for you? It's simple, you can't do anything about it at all and there is no way to get into it now onwards. The thing is when you create a account you get notified by the MEW many times that you should save your private keys and keystore file somewhere safe. But people don't even care to read it and just rush to get into it.
While creating the wallet you are prompted to download the keystore file, so if somehow it is in your history or in the downloads then you could be lucky enough to access that wallet.
Otherwise there is no way to get into it.
