Jenn,
Just as Lit Love, I too get infuriated at those people who abuse the handicap parking spaces. To the point, after watching the driver and passenger/s get out and all walking fine, that I want to approach them and ask just which one of you is handicapped? But my wife restrains me (lol) to avoid causing a scene. Which would probably happen because stupid people usually defend their actions with stupid reasons.
I had this discussion, calmly (lol), with someone once and his opinion was that since he paid for the handicap placard he should be able to use it whether he needed to or not at the time. Some people just don't get it!
I'm so sorry that you're going through this. I, along with everyone here, can relate to your trials. People can see my wheelchair or my cane and can witness my inability to walk right, but they can't see the constant pain I'm in. Most people respond in a helpful manner and are very accommodating but every now and again you run into those that just don't get it. Or even seem to care. Grrr!
Remember that cliche about not really knowing someone until you've walk in their shoes? In living with this monster the saying fits.
Here you find people walking in the same shoes that you do. For what it's worth this is the place to vent. Someone will always lend an understanding ear and even at times offer some witty piece of info.
Sorry for the long winded dribble. I tend to get carried away sometimes (lol)...
