you're human. a person can only be a human. some people are psi vampires, some feel they have the spirit of an animal inside them, but you're human. if you believe you are a witch, it doesn't change the fact you're human, it just means you follow a more magical path, strive to learn, and try to be 'of the earth'. [recycle for instance]
magic is real, but there are limits. magic is energy found in nature. magic is using this energy to influence your life for the better. there are limits, if it's against nature, it cannot be done. you cannot grow wings, turn invisible, transform, and so on. magic can be used to influence love, health, wealth and luck, it can be used to cleanse, protect, even curse. but real magic [k] isn't something you see in movies or tv, learn about real magic [k] before going any further.
