I got this comment on the very last episode of the previous Web-Comic I wrote. (I am providing a print screen of the comment below.)
I was in a bit of a shock when I first read it, but thankfully it was the only one among many positive comments so I quickly got over it and moved on. This comment made me understand the saying, you can't please everyone, so just write for yourself. Make sure that if at least one person likes your story, that person is you.
The hurtful comment said:
Beyond this one comment, I have received many other comments from people (but usually in private) telling me what they didn't like or what they believed didn't work in my stories. I always see such feedback as opportunities to get better and none of them has actually ever hurt me yet.
I have also been lucky I guess, so far, to hear from people that were professional in their approach and they either didn't want to hurt me or were kind enough to take the time to offer constructive criticism that helped me understand their P.O.V and helped me become a better writer (or I hope so anyway ).
As for rejections, that others have mentioned, yeah I received plenty of those as well, and even though they can sting, they are unavoidable and anyone who is serious about being a writer (of any kind) will have to learn to deal with them I think. The worst I ever got from being rejected was a temporary lack of motivation before I got back to writing again.
