I know how you feel!
the most frustrating part at the beginning was all the docs saying or 2-3 weeks or months and you will be right as rain....HA!
I have had between 4 and 15 concussions in the past 3 years and I am getting a little better, but then it comes back and sometimes the only reason I get out of bed is because otherwise my parents or friends will worry. I am kind of scared of moving into my own apartment this coming year, because I am not sure that I will be able to convince myself anymore. I am so tired. tired of living like this in my early twenties! I want to be able to run across the parking lot without collapsing at the other side in pain!
The biggest thing I am tired of is the clumsiness which keeps getting me more concussions. I really think that I am going to have to start wearing a marshmallow helmet!
GRRRRR! Why do human beings insist on trying so hard? Why can't we just give in?

but then again I guess that is why the human race is so wonderful!
Well, on those happy notes,
Merry Christmas!
