Storage disaster!

Storage disaster!

So I am a college student and I have a nice little room that is barely 11x12. I have two closets and thought the space would be enough...turns out the stuff barely fits. I know I have a bit of clutter, but I have been throwing out stuff and it never seems to empty itself. Does anyone know of a storage miracle that would help me with clothes? I tried putting shelves in but the dry wall is pretty flimsy... and a dresser wouldn't fit in the closet...
