I have read articles, written by seemingly reputable sources, that try to state by this time or that time after the trauma we should be all better. But I think they're just trying to make things simple without knowing what's been damaged inside someone's head because without a microscope that can see inside someone's skull they really have no idea. And they really have no idea how long it will take either. And neither do we.
The accident I was in was about 18 months ago and I'm still making noticeable improvement. But I too, am awaiting the day I can come onto this forum and say - "Hey! I'm all better!" But I'm a lot better than I was just 6 weeks ago and much better than I was 6 months ago, etc..
I think the best thing for me is to continue to have hope that I'll get better and that hope takes me through every day to more healing. I think time is the best medicine for a brain injury.
I read an article about a woman who didn't even know to get cognitive therapy for years after the accident she was in and she made leaps and bounds worth of improvement well past the X time mark that is "typical".

Just try to hang in there! A lot of us here have had a bad year or two (or more) recently too...
