Twilight Sparkle isn't very normal, but she already knows this. It's just one of those things she deals with on the day to day. Of course, comments from the peanut gallery don't really help, and neither do surprise parties. But thankfully her therapist is there to help her through her days and can help her thoughts get sorted out.
And the peanut gallery, too, of course. Sometimes they help, as annoying as they can be.
