I know what you mean. There has been a lot of times where i have felt the exact same way. I've been here for almost 6 years now and I think at times it would just be simpler if I left. I hardy get any feedback at all, and when I do it usually is rare. In the long run though, I continue to choose to stay because of the friends I've made through this site and because I continue to hope that things will take a turn for the better. Just try to stay positive; Cherish the feedback and support you get, no matter how much it might be, and remember that there are people here who love your work and cant wait to see what you do next.
