Hi, took me a few days to really notice that I even had vampireish tendencies! Dumb I know...I am not very popular in Morthal, I seem to have upset them and now have quite a large bounty on my head. All i want to do, if possible, is get to a bleesing stone and get my curse removed. Can I do this?
Not if you have evolved into a full Vampire.
You can only cure the curse/disease in the initial stages, which is within 3 days of getting bitten.
It sounds like you are not only a vampire but at the final stages (4th I think) this means that each and every NPC will recognise you as a vampire and attack, or refuse to speak to you etc.
You need to feed on a sleeping NPC and this will revert you to stage 1 which will alow you to speak to NPC etc, then complete the cure quest.
