I can also relate the having to have stores and store employees help with carrying and loading the cart and/or the car....

In a few circumstances I have had the employees act a bit rude when I ask for help since I don't look sick. I look like a 'healthy' 30-something, so I used to get store employees that would roll their eyes at each other or act a bit rude to me when I asked for help.

But now I don't have that problem at all anymore.... because when I go shopping I put on one of my wrist braces, or my shoulder stabilizer, or something visible.

This does 2 things for me -

1. it's helps me to remember to be cautious and helps me remember to ask for help... it's very hard to lift anything heavy when I have a wrist or shoulder brace on.

2. it gives the store employees a visual. They get to see why I need help, and so they become more than happy to offer help or to give help when I ask.
