I know that fitting in dA is so difficult at times. I've been to this dark spot a long time ago and I still am. It sometimes feels like no one appreciates your work because all people do here is to clap for the amazing pieces (and awesome artists) while ignore the less famous but improving artists.
I've been a deviant for almost five years now, but only two years were spent here. The other three years consisted of me chasing my other dreams. In those two years I've been here, I had a lot of fun doing what I love but I was constantly disappointed when no one sees or appreciates my work.
But the reason why I am still very active on my dA now is that this is my dream. Art is one of my passions. To hell with page views, faves, and comments. I remind myself of the silver lining at the end of the journey. I remind myself that the great artists all had to experience pain, suffering, invisibility before becoming good at what they do and before becoming famous. I remind myself that hard work and kindness is always rewarded with good karma.
You might feel like you are not welcomed, but keep trying. I have met people in this site who have made me feel like I am a great artist and a great person. They push me to improve and they make me feel like I always have a family to go back to.
Then again, if art is not your passion, it is going to be tough road. I know you've tried fitting in, and perhaps you need to take a break, go back to the real world, and live. What's important is you live your life to the fullest.
