Blue always has the right words to say
I can relate to what you are going through. I also am 35 and having to use a cane to help me walk due to knee issues and I get dirty looks and everything since I parked in handicap and have to use those motorized scooters in stores.
With people closer to me I am always dealing with questionable looks and I just keep them at arms length. The ones that do care have done research on all that I'm dealing with so they know and understand a little better.
Hang in there.
