Really interested but still skeptical

I'm a 22 year guy in Canada going through some horribly rough stuff right now, and I have been interested in witchcraft since I was very young. It wasn't a casual interest, rather I'm quite taken with the idea but all my life I've been a hardcore Christian my parents would have flipped if they knew I was interested, (I also thought it was evil) so I avoided witchcraft and magick. Now I'm no longer a Christian and I want to get into witchcraft but don't know how. All my life I've seen spirits, (I even got checked, I'm not schizophrenic) I've had a draw to the supernatural, and I seemed to be able to read people. I guess I'm rambling. I'm interested to know what sort of things can be accomplished with witchcraft; basically where does reality end and fairy tales begin? Is it possible to heal with a touch? I'll stop now. Please help.
