Deal with your loss and find out how your account got compromised, most likely you have visited a phishing site.
My mine have a same thougt with you, to acces MyEtherWallet account is difficult for everyone (especially hacker) cause they need a private key or anything else to get in. A few month back, I had found many user MEW who got hacked and their token was stolen. Those are caused by phising site, a hacker made a counterfeit site like MEW precisely and lead on many user to use that site. In the end, if they are successfully logged in, all your important documents such as a private key will be known by a hacker who makes the site phising.
