can't open storage door, stuck on the other side

Hi, I have a small storage and I can't open the door of my storage because I think my suitcase is stuck just below the handle of the door so if I try to open it, well, it's stuck. I've tried unscrewing the handle but it doesn't even work, the handle is still there and not falling off if that makes any sense. Anybody have any ideas how I can fix this problem? :( Your help is much appreciated!
