If you're afraid you were hacked change your password, if you can't access your account contact the company directly. That goes for any service not just Minecraft. You might have to email them back again, the site may say 1-2 business days but that's just a rough guess. Only people that can help you are Mojang. Have you tried just resetting the password?
If you believe you have had your passwords compromised CHANGE THEM ALL IMMEDIATELY. That means your email, Facebook, EVERYTHING. Last thing you need is Mojang emailing you back and you don't have access to the email.
In the future be more careful. Be careful what you download and from where, get some antivirus running. Most people get a keylogger or trojans from downloading fake hacks or cheats or something similar.
If the only proof you have that the account is yours is those screenshots you're out of luck. You need to have the email linked to the account.
i HAVE the email that i previously used. but the email won't work apparently if i'm not getting a reset password.
also nothing else seems changed or anything like i said i might have just been unlucky.
