When I was early in on in my injury, the neurologist I saw, who didn't ask me a thing about what happened and what I'd been experiencing (and I wasn't well enough to realize I need to stand up for myself) said "you don't have a concussion, you PTSD, take these pills).

I became very defensive with everyone around me and made it my mission to convince the world. My dad and sister pointed out to me that I don't have to waste my energy on that. Just do what I have to do and concentrate on getting better.

You need to concentrate on getting better. Using your energy to convince people is a waste of healing energy. So, keep close to those who are supportive and take a break from those who aren't. Eventually those who realize that you're doing what you need to do will stop giving you their two cents and just be supportive. Those who don't, well, you don't need them right now. Maybe later.

Good luck.
