This site sells journals you may use as a spellbook, as well as various other books that teach magic.
I might also suggest that you do not need help with all of the spells you can get. You need help with learning how magic works, the nature of its existence (what it is), and why it can be of use to you in your life (and why not).
Or... you could just scribble down spells and try them all. Up to you, really.
