this problem has recently gotten much worse, for the longest time the top corner of the door had been gently rubbing the door frame and wouldn't shut easily. Well now something has happened and the door hits the frame and I must gently lift the door to make it pull closed.

Basically the door is not hanging square with the door frame and causes it to hit when you try to close the door. is there a way to raise the door so that it closes properly? here are the pictures of the door and a closeup of where it hits
