Can't unlock the full Bend will shout

I'm on the [AT THE SUMMIT OF APOCRYPHA] quest line where I have to unlock the bend will shout.. I have already learned the Earth but of the shout but I can't learn Mind and Dragon because I don't have any dragon souls saved up, And I can't absorb any more souls thanks to Miraak stealing them all from me.

Anyone know what I can do or is it game-over for me?
