I am sorry to hear of your rough morning.
Those symptoms sound very familiar to me! I have had moments where I feel a strong urge to just lay my head down...very strange! I think it's likely our body's way of telling us we need to rest and relax.
Did you mean to write that you took an Ativan? If you find relief in the use of a benzo...that is pretty indicative that you were indeed dealing with anxiety symptoms.
Practice yoyr coping skills as well...and give yourself permission to take it easy today!
