OOHHHH!!! I had the chance a few times already to feed but I didnt because I had thought that may make it worse. Do you know the best way to find people sleeping or places? And how many will I have to feed on? Thanks guys for the help. I greatly appreciate it.

You will only need to feed once to bring you back to a state where you will not be attacked on site. ( I THINK,not sure dont play as vampire).
Then you will slowly progress to a full vampire again. (again not sure on time here).
Finding someone to feed from should be easy enough , just sneak into a house at night and find a sleeping victim.
