Approved Sleeping Aid, But Not Allowed to Have It

My health has gotten worse and my breathing as well. The P.A. here, named Schafer, has approved for me to have a pillow to raise my head up in the air, so I am able to breathe. I have a pass for this pillow but the laundry and medical tells me they don’t give pillows anymore. So why did the P.A. give me a year pass to have one?? However I still gasp for air and my health is bad. Any way if you can help on this I thank you. I filed a grievance on this, still waiting to hear something on that.
