Not bad
Your flash has potential. It has appropriate music and I think your flash has a good idea, showing people how people with low self-esteem or depression, etc. feel on a day-to-day basis. I would only suggest a few things that you could add (they're just simple problems, though, so you've probably heard them before): a preloader, an ending, and a story (not necessarily anything super long, just a bit of storyline and maybe a little background description on your character). I'm saying this mostly because the loop startled me (I thought there was more until I realized it simply looped). Other than that, great job!
