Post it, and then run away for a month. If nobody says anything, that means either nobody reads it or it's not as bad as your worries are. If someone say something, take a deep breath, click it and see what that person says. Take a deep breath, release. If at any point your cheeks feel hot, stop reading. In many cases, the comment is not actually dissing you, but you feel defensive when the comment specifies what's wrong with your stuff.
Don't get angry, yet. Unless they're clearly insulting you. But even so, sometimes it's just how they say it that comes off as insulting, but their criticisms are actually valid.
Don't need to draw attention and ask for feedback if you can't handle it. But if you do ask for feedback, be prepared for those douchebags who just want to bring you down. There are people like that, but here in SH, they're kind of drowned out by those who do want to help you out.
