I have primary progressive multiple sclerosis and it's as bad a hell as I ever want to face. I've been confined to a wheelchair for the last 5-6 years, give or take and it's like you say, you can't see any problem, other than me being in a chair now but, if I do go out, (pretty damn rare), I feel like people are looking at me like there's no reason for me to be using the store's power chair and it was even worse when I still had some ability to walk.
It would be a breeze if it was just a matter of losing my legs, shit, I could be active as hell still. No, that would be too easy for me, it's doing the same shit to my entire body, it's just that the legs are the most heavily affected first, being the largest of the extremities.
For a while now I've noticed the sensation and the fine motors skills going in my hands, especially my left and I've always been very good with my hands so it was something that I feared more than some other things.
Feels like a lot of shit is falling apart in my life. To hell with feels like, a lot of shit is falling apart and has been for some time. Me mostly.
