TUMBLR HELP?!? PLEASEE!!!?

ok so some of you may know what tumblr is. but anyway mine was hacked, at least i think it was. there was this page that came up that looked like a page from tumblr asking me that i needed to verify something and log in again, so i did. but i read something that said if it didnt have a "follow" button then it could have been fake? anyway, my dashboard and stuff is working but when i click the link to go to my blog it just says "http://tumblrlogin.com/?brupM" and it says its loaded half-way but then it just stays like that forever.. PLEASE HELP ME if you can!!
