Really uncanny, you are right. I can't believe that others share my fear of these three little steps to board a bus. I can still feel the anxiety seeing the bus slow down at my stop... "Will I be able to board it normally?"...
Yes, the "bad knee" excuse really helped as it explains what they were seeing, made sense and closed the discussion.
As for medication, I am not too keen to take any at this point (unless someone convinces me that this is life changing). I managed for 35-40 years to function relatively normally, there is no suffering per say. I am tempted to manage the disorder without medication. Now at least I can say that I have a very rare and diagnosed disorder which explains why I cannot do everyhting that other people do easily...
