I'm new to the elder scrolls games and skyrim is my first game but I'm stuck in a bug i think and it is so annoying!
I was doing the laid to rest quest and i had to kill the master vampire, however I'm level 7 and he is to powerfull for me so i can't defeat him.

Now with that quest somebody is following you and now for the whole game a person is following me that wants to help me kill that vampire but i have to train some more.

Now I'm a vampire stage 4 and everybody attacks me including the person who is following me. So every fast travel every house i go in he attacks me so i can't sneak on somebody and drink their blood because he is in the house to then and he fights me so the sleeping person wakes up.

I've been trying for over 3 days to drink somebody's blood but i just can't get rid of that follower .. and even if he was away passing the guards at a low level is also very hard. I just want to become normal again because vampires svck! I can't do any quest i can't do anything

Please help me

Can't you just kill the follower?

Not sure what you can do now but if you had talked to the guy before you went in the cave you could have told him to go home. As for the vampire infection you need to get it cured early you can do this by a potion or a blessing from a temple shrine.

I'm sure there is a cure for vampirism but I don't know it.

PS. have you tried killing the follower?

No if i kill him then he waits for a couple of minutes and then he tries to attack me again and every fast travel,rest or when i go into a house he will be back alive no matter what
and when i was a vampire stage 3 then i could say to him to back off but then he would follow me anyhow

You can cure it with a quest ..
but i can't do the quest if the quest giver attacks me when i see him ..

Sounds like a horror movie

It is driving me crazy
I really like the game but i won't start over and if i can't fix it then i have to trade the game

You can use a console command that should cure you:
setstage 000eafd5 10

That is if you're playing on PC. Otherwise I don't really see what you were even thinking going vampire with a henchman.

Also, you yourself propose a solution to your dilemma:
During these few minutes you have more than enough time to sneak into a house and feed I assume?
And sometimes in forsworn camps people are sleeping outside in tents so you can use that too if going indoors automatically drags the henchman with you.

I think being a stage 4 Vampire you should have access to a calm power. Try casting it on your follower then trying to feed.

Try this, get some light armor if you have any, and daggers, that should render you completely silent when you are in stealth, in addition to your invisible power, and wait till its night, then go into a village and pick some lock and there you have a sleeping body to feed on, if hes awake just run away and try again on another place

Try finding a hunters shack, small house or farm in the worldspace.
there arent any guards hindering you there.
Try to use a spell to calm your follower, then sneak and feed quickly.

Good luck
