Dude, I like your take on things, but could you use the enter key once in a while? Sometimes it's fine, but the wall of text a few posts back left me with a headache. It wasn't even poorly written - just unbroken.
I heard this voice as I was reading it:
Picard's description.

Parents never understand very well when their child ends up not being well-adjusted - or at least not well-adjusted enough for their own purposes. I wouldn't worry about it too much, most people have absolutely no idea how children think even if they used to be one - it no longer makes sense to them, so they write it off as being abnormal.
Elementary-High School is a kick in the teeth if you're not 'normal'. Kids are about as understanding as brick walls, and they aren't capable of seeing past the exterior. If you look a little weird, they're going to assume the worst. Charles sounds like an asshole, so I wouldn't concern yourself with how he came to view you later on - not worth the effort and worry.
As for the medical issues, I really haven't got much advice. Seizures can be acute and brought on by nutritional deficiencies or other conditions - they don't always signify a chronic problem. Spinal taps can be done incorrectly even by seasoned professionals, and doing two in one day sounds like a nightmarish mistake in etiquette. My mother still gets back pain around where she had a spinal tap 20 years ago.
As for the chest pain, I'd go see a doctor. Even if it ends up being nothing terrible, you should still have someone check it out - especially considering the lingering effects. A few years back I came down with a bad cold that was on the pneumonia level, and ended up going to the hospital because I was having trouble breathing.
During the check-in, they found my blood pressure was 210/155, which is nearly double the normal 120/80 - they rechecked it 4 times. Now, it's normal for your BP to spike due to an illness, but that was on the stroke-level of ridiculous. Basically, I was on the verge of having my heart explode or my veins starting to tear apart, so I was immediately put on medication to lower it, and I've been on them since.
When not medicated and otherwise healthy, my BP hangs around 150/100, which has caused, apparently, chronic headaches, insomnia, and other nasty symptoms for years that I passed off as normal. If I don't keep it down, it can result in chronic heart problems down the road, and that's just plain frightening.
Had I not gone to the hospital, there's a real chance I could have had a stroke or some other cataclysmic event. That's not a calculable risk - get it checked out.
