Please don't give up hope Wakey.

I have had PCS for more than 2 years. For a long time (about 18 months) my recovery plateaued at about the same level as you are at now except I also had bad sound and light sensitivity. All the doctors said they could do nothing for me, that only time would tell if I would be stuck this way forever. It was a terrible existence.

But with another 8 months and a rehabilitation program specifically for mTBI (that I had to look for, and found on my own!) I am now able to live an almost-normal life. I can exercise moderately. I use the computer for as long as I like. I can listen to music if it's not too loud, watch TV or movies if there's not too much fast action. I bike and take public transit everywhere. I hang out with friends, and I volunteer regularly.

Am I 100%? No. But I am getting there, slowly. Will I ever be 100%? I don't know. But I guess what I am saying is, it will get better. Keep looking for the help you need. Don't give up hope.
