Why I Don't Like Sharing My Writing

I really don't like sharing my writing because sometimes my writing doesn't sound the way it should. I still do think sharing my writing is a good idea because everyone can input what I could improve on and make my writing even better than it already was. The thing I fear is everyone making fun of the way I write or the way my essay sounds. However, I do know that it is for the best and can make my entire essay better, and maybe, and get me an A or B+ on my essay which would really be nice. I still think my fear is just nothing because my essay could be the best in the class.
