Well, we had no way of knowing these details until you told us.
So do it in stages. Take a briefcase to work with important stuff in it, or a backpack, and leave that stuff locked in your desk. Get a safety deposit box for important stuff and only put your own name on it. Mail things to your own parents or siblings or anyone else who can help you out. Do these things if you really want or need your possessions.
Or do what we often tell women in this situation: drain out as much cash as you can, pack a small bag, make sure you have things like stock certificates, real jewelry, bank cards, and go. And you'll lose your fishing poles or your chair or your winter clothes or whatever, but you'll save your own life.
