I don't know how many times your daughter visits and needs the use of the bed, but I would eliminate the bed. Purchase one of the airbeds. These beds inflate and deflate in a matter of minutes. Mine folds right back up and fits in its original box which is about 6"x12"x10." They are very comfortable. That will give you some more room. I would retrofit the closet for shelf and bin storage. Just a few ideas here:

You may want to pick up some used upper kitchen cabinets and mount them above you on the wall for storage. We have a ReStore that contractors take things like that to and then you purchase them for real cheap.
Good luck!
