Two small stairs creating anxiety for my husband

My husband and I live in an apartment on the first floor. The only problem is that there are two stairs total to get in and out, one out of the parking lot and the other is a small one to step into our door way. He can walk, albeit slowly, but its like he gets scared to step down. Mostly, its the going down that bothers him.

Getting to his appointments or even just getting out to have a bit of exercise is exhausting for me, and sometimes I just keep him inside because its too much of hassle. Has anyone experienced any issues with the stairs?
