i like what Makoo and chainedbeast said.
meditate, find somewhere to sit and reflect. you don't need to practice magic to be Wiccan, you should tell your nah saying friends that. i'm not telling you to be mean and turn your backs on them, if they wish to do these things, explain a couple facts about what you believe, and if they still don't believe you, you are better off without them. again, do what you feel is right.
there have been times where i've felt similar, i wonder if this path is right for me, i have a coven make up of mostly friends, but we each believe something different and a couple of our people in the coven are rather negative when it comes to others beliefs. i close off a bit and stop practicing. i too am a writer, and an artist, so i focus my energies on other things. eventually though, i return. i could be nothing, it could be a nice day out, or it could be i feel like meditating, or a dream i had. but something will always remind me of my path, and i return and i feel so wonderful. i don't let my faith consume me, and i don't brag it up to other people, but there's just a feeling i get. i guess it's the same feeling anyone gets from faith, i feel calm and happy.
i do some reflecting, go for a walk in the woods, or a park, meditate like i said, do something calm and nature based where you can think and decide if you feel it's right, if you feel happy, if you can see yourself doing Wicca in ten years, or twenty, or sixty years.
[one more quick suggestion, might not have the same effect. i love the movie Practical Magic, it's Hollywood, but at the same time accurate. not everything mind, and it does have romance involved which i'm not a huge fan of, but the parts where they're in the house, or telling the story of Maria, i love those, and i always get inspired for some reason. you could try that.]
