First world problem

I have severe ptsd and get super scared at anyone being at my front door and me opening it to them breaking in. That being said I always choose the leave at door drop off option and have insanely explicit instructions for how to find my apartment. For some reason drivers still always want me to come to the door and it scares me so much because I feel like i’m just waiting for something bad to happen. Does anyone have any insight into why they do this?
