I have this problem a lot too and the only thing I can say is that it's your writing and that you should be proud of that. There's always a chance to better yourself, and practice makes perfect. I feel like my writing is not the best sometimes or that people may not like it, but my writing teacher once told me to write every day so that I could get better. I firmly believe that. I write even if I don't want to publish, not only to satisfy that feeling but to better myself in the craft! Be proud of your work :) Hope that this helped in some way.
