overcome your obstacles
One of the biggest reasons why you mind find it difficult to find your voice, is a fear of rejection or humiliation.
I personally found it quite hard to live out my “Christian-based” voice during University. Religion (despite of our constitution) is something I feel that is frowned upon in the High/Academic Art World.
Your specific voice might not be something that is widely accepted in certain circles. But my encouragement to you is be brave, you don’t need to fit in to be important. Those that accept you and find your work inspiring is all that matters, the rest can go fly a kite.
Second obstacle might be that your niche is so unique that it is difficult to find artists/art communities that specialize in your voice.
But like an Artist friend, once said to me:
“If you can’t find the art you want to create, be the trendsetter and start a new movement. Others will follow or you might be surprised who you discover along your travels.”
