i know the feeling. i've been asked some tough questions in my time, some have really made me think, but there is not universal right answer, just the right answer for you. example, a friend of mine found out i was Wiccan, and she's now a youth minister, she said once 'i know you're a good person, but in my heart there is only one god, and no matter how good your intentions, or how peaceful your religion, you are being deceived by the devil' that's always stuck with me, and i really thank my friend because that really elevated me to another spiritual level. you can't prove or disprove our beliefs, so i did spend a day or two wondering if i was being deceived, but this caused me to soul search, meditate, research, and on my journey i found my matron Goddess, i found more about myself, i deepened my spirituality, and my path became more open and real for me.
i unfortunately cannot give you a right or wrong answer, you need to figure it out yourself. i would try making lists and journaling [but that's me, i'm organised like you would not believe] make a list of beliefs, a list of why you feel this is the right path for you, journal how you feel, what you think, your experiences in circle, or on a walk, little things you noticed. perhaps go to church, or read the bible, or any other holy book. it's good to see others points of view, but you can also make notes about idea's in the faith you agree and disagree with so you can make a better informed decision about what your path is and is not.
at the time i was speaking with my friend [when she made that comment] i was... not lost per say, but just going through the motions, and while i believed in the Wiccan path, i didn't have a strong connection with the Lord and Lady. hearing those words was the kick i needed to do some hard work and dive deeper into my path. if i hadn't heard those words, i would of never found my Goddess, or my God, i also wouldn't of found new Pagans to speak with and learn from. perhaps you'll discover this is the right path, or maybe another path is right for you, but don't be afraid of looking. you will be asked 'why a witch' for the rest of your life, it's nice to know the why for yourself. good luck to you.
