If this sounds like what you want then I'm going to give what is for me an unusual piece of advice. I'm going to suggest that you start your knowledge of the craft through book work. Normally I suggest approaching a Witch path through intuition and hands on practice but in your case I'm not sure you understand the basics of what being a witch is all about so a strong foundation of knowledge is essential. If after a book or two you decide that following the path of a Witch is what you definitely want then your enthusiasm and love of nature will be invaluable to you as you continue down that path. The book I am going to recommend you begin with is "A Witch Alone" by Marian Green. I'm specifically recommending this one as it is linked very much to a Witch's relationship with the natural world and I think you will find it suits your outlook.
I'm also providing you with a link to a similar question I answered recently as I think you will benefit from the advice. How do I become a Witch?
As for does being a witch work out... Well I'm doing very nicely thank you!
