Wisdom teeth removal

So, I have to have my bottom 2 wisdom teeth removed. One is partially out with a big cavity and the other has never started trying to come in. Needless to say I am scared shitless. I have premature ventricular contractions and the thought of being put to sleep scares me. I'm scared they will put me to sleep and I won't wake up. I'm just so scared I haven't even been able to eat or sleep. And the pain I've heard about after scares me too. ☹😕
