Besides what you did , how about
Slide open the pilots door window and get your external reference out of the hole.
If you can't cope with that small a view of the outside world then if the cabin is secure, open the door and look out of it. should give you enough references to land and sort out the visibility problem.
Obviously opening the door is not ideal in some circumstances but perhaps better that option than crash into the ground because you have lost external reference.
Were your clothes wet ?
