Call Twitter ASAP. Delete the account and creates a new one.

hijacked? just reset you password using alternate email or security question if not you can always hack it back.
ps you can also send a report to gmail.. by clicking on forgot password and following procedure .

To delete your Google account sign in here:
https://www.google.com/settings/account
Scroll down to 'Account management' and there will be two options:
Delete profile and remove related Google+ features.
Close account and delete all services and information associated with it.

I believe the second option will include Gmail.

try to log in your original FB using another Desktop or Notebook and then you may able to terminate your old FB

Access http://www.hotmail.com and click "Forgot My Password".

You'll be asked the "secret" questions that you chose when you created your Hotmail ID.
Correctly answer those questions, and you will be allowed to login and to set a new password.

Hopefully, the "hacker" has not deleted your "contacts" and/or your E-mail messages.

Yahoo might be of help but since both emails are gone, you are probably sunk.

My first guess would be to delete all email accts. in hotmail and un install msn messenger, and create new ones.
