Hacked e-mail account.

My hotmail account is hacked and the people who have hacked it have access to the rest of my social networking sites, I called microsoft and they said to post my problem here. Whoever hacked my account has access to my twitter, facebook and rest of social sites so could I please get help as soon as possible. Also if its possible, could you e-mail all of my social sites that my -email has been hacked? Because my twitter account has been hacked also and I cannot change my password because my e-mail connected to the account is hacked.
