Turning into a vampire is too difficult, long and its consequences are not only psychological, but sometimes physical if you do not control yourself. If there are no reliable, close people nearby.
And so your story began, you were very young when you got into a rather large but loving and caring family. Until a certain moment, you did not know that these people were hiding a very important fact about themselves from you, but you suspected, because it is impossible not to suspect here. They are vampires. Like you, you will become soon.
It was an autumn, rainy day, which was already approaching lunch. School, or work, as it may seem to someone, but no, for you today nothing meant as how reincarnation. You were scared and at the same time curious about what feelings you experience when you transform into a vampire.
Carlisle injected you with a small amount of sleeping pills so that you wouldn't feel these... "nightmare feelings" as he said, and then he left. You were lying there and already felt like you were literally asleep, but not completely, when you heard someone enter the room and close the door behind them. A few minutes passed, as if... Carlisle couldn't get his head around the fact that he would actually have to do this, again transform person into a vampire.
Finally you felt the touch of a cold hand on your warm one, and then... A bite right on the neck.
