I get that a lot too. I used to post art years ago and I'd get nervous if they'd get viewed or liked by anyone. That's why I don't post my art or do it anymore, I'm scared I'd be disliked or my art wouldn't be 'good enough'. Just from here I get the feelings too, I'm happy to make a post about something, but then later think I'd might not get a reply from it and start to worry it might not be appropriate or look right to some people.
