There's actually a varied difference of opinion on that. Some say that if you stay in there long enough, and wish deeply enough, things will crawl out of the woodwork of your mirror-frames and even your reflection will begin to talk back to you. Then your closet becomes the proverbial 'wardrobe' to Narnia, and your internal gender conflict will seem like a lion battling a witch.
just sayin...
ps: you could also turn into a moth. Moths can live for years in closets.
