It's possible, but I'd recommend going to the hospital (don't drive ambulance if needed) and telling them what happened, making it clear there is no intent to harm just fear of carelessness due to effect, and work with them until effect subsides. That being said you'll likely recover especially if you can sleep although if it's affected your ability to breathe don't sleep alone.
Honestly though the type of stuff your seeing is indicative of some unresolved past issues stemming from your life experiences. Even when this resolves I suggest thinking about what instincts and emotions led you to think about something rooted in the idea of evil, suffering, pain, and anger directed towards self in relation to perspective of the external world.
