Help! Severely dry cracked bleeding lips!!!! SOS?

Ok, so I have always had a little bit of a problem with keeping my lips intact. But it was easy because I developed a habit of putting on lip balm so much that my friends called me Chap Stick Girl. Then I left my lip balm in my jeans once, and now my lips are disgusting. They are cracked, bleeding and really red. And I have this (this is nasty ) slab of dry, dead skin on my top lip. I really need help. I have tried Vaseline, olive oil, that sugar scrub thing, and lip balm but it doesn't work. HELP!!!!!!!!!!!!!
