I have that problem too, always bruises all over with no idea how I got them. I bump into doorways a lot, or can't find the stair rail, or miss my mouth and dump my water glass down my shirt... people just think I'm scatterbrained or have crap depth perception. On very bad days I used to have to feel things out while moving around my apartment.

I was getting tests for all sorts of neurological stuff before we figured out what was up.

And I very desperately wanted firm answers for what was going on. Now that I get that "what is going on" is something I created, I have an easier time accepting the things that come up, that they must have some sort of protective function.
