You ask if you are meant to be a witch. I think you are phrasing the question with too much emphasis on predetermination and not enough on what you want or what feels right to you. Do you feel called to witchcraft? Do you think your natural gifts and personality would be a good fit for the craft? Have you looked into witchcraft enough to know what it is, what it involves and if is something that you can see yourself committing to?
Sometimes life does give us a shove in a definite direction and I've spoken to several witches who have been open on the subject of how negative circumstances in their life have led to them starting to practise witchcraft and taking back the power in their lives for themselves. If you feel your life is guiding you toward a craft path then it is certainly something to consider seriously. But ultimately practising the craft is a choice and it is up to you whether you want to pursue the path of a witch or not.
