Yes i go into the sun and it says my blood is boiling. is that the reason and how do i get rid of that? I have been to the shrine and it said all disease is gone......
Go to any inn and ask the innkeeper for local rumors, it will give you a quest to cure vampirism. Since you're hated try small towns like Riverwood or Rorikstead. Also you have vampire powers that make you invisible and force enemies to be friendly to you, these can help getting the quest.
Alternately if you want to remain a vampire and not get attacked, you must feed on a sleeping person. If you feed regularily you won't get attacked on sight.
