Re: Cahier position
This is a letter of request to keep me at/as the cashier.
I have a fear of having people surrounding me. I see the register as my barrier from the people. I know I will not be closed in. I know that being on the floor is going to create a panic attack, that’s if it’s not on a busy day. I honestly do not want this for me or the store. I feel very comfortable where I am at. I feel less anxious. I needed to commiserate with someone else that has one iota of a chance of understanding what I mean and how I feel. I will improve the area that concerns you most. Attached is a copy of my doctors medical finding to my fear of crowds. These finding are based by my doctor and SSA.
