So sorry you are going through this at that age. I see many others your age at my various therapies and wish their parents understood better how incredibily hard daily living is with a brain injury.
I'm slightly older than you, (was in the middle of grad school/working full time, seriously relationship, time for big girl decisions about houses and cars and such), and then my world fell apart after a car accident.
I have tried throughout my recovery to get old collegues, my boyfriend (who really tries so hard to get it), my parents, my teenage brother, etc. This article, although related to lupus, helped my family finally get it! I hope it helps you.
Even though the woman has lupus, I feel like the cognitive and physical fatigue we battle daily is very similar. The point she makes in the article is applicable to us as well.
