I had epilepsy when I was little! I didn't have seizures like how most people with epilepsy do, I would just be unable to move (but still breathe and blink, I guess?) while being fully aware for the duration. Apparently I was pretty bad for a while (I was 5/6 at the time, so I don't really remember that much), where I had a lot of coordination and mobility problems, and spent a fair bit in hospital. My parents tell me scary stories about that time every now and then, and I am kinda glad I don't remember it. I was on medication for a while, but then it went away! I had to be careful around puberty in case it came back, but it seems like it has gone for good (at least at this moment in time)
I remember being sick and in bed and knowing my dad was there next to me but not being able to move at all, and remember being in the hospital and having to colour in with my left hand because I had a drip in my right, and getting frustrated that I kept colouring outside the lines. I also remember my brother was able to go play in the games room and I wasn't, which was totally unfair, and kinda remember having to get a lumbar puncture, but I think that is more from what Dad told me (he wasn't allowed to be in the room with me, and could hear me screaming from the hallway) than what I actually remember.
epilepsy: scary stuff.
