So umm, what happend to eating/drinking

It seems like when eevr I am doing the dailies in blades edge, and I try to eat/drink, I randomly stand up for no reason at all. I don't move, am not attacked, I would click the food and sit, a second later I would stand. It is annoying because I am wasting food/drinks and not even getting healed.

Oh and no this is not the char I am playing on, using my warlock.
