Cfs and mild concussion

I have chronic fatigue/Dysautonomia - waiting for ME assessment, but it's pretty clear I have it. (Fatigue, post exertional malaise, )

5 weeks ago I hit my head and have had horrible concussion symptoms ever since. The initial agitation has passed now, and I'm really struggling with not being able to tolerate anything which needs cognitive processing. (Someone is posting this for me).

I can't read, watch tv, listen to podcasts...... I have to lie in semi darkness and quiet.

I'm getting very depressed and thinking what is the point of living like this.

My GP says he can't do anything until it's been 8 weeks, then he'll refer me to some team or other - I don't know.

I know there's a good chance I'll recover but equally there's a chance I won't. How do people live like this?

Any experiences especially positive, welcome.

Thanks
