Thanks for all of the support everyone! It is fabulous to have a group of people to communicate with who have a similar experience.
I see a lot of comments that I should not have returned to work so soon. I'm in the U.S. where it's dog-eat-dog and every man, woman, and child for themselves. We're not expected to be sick, and if we are, we either fend for ourselves or go bankrupt.
I could have remained out of work for 6 months on medical leave, but my vacation and sick time were running out and I would have been without pay. As I live alone and all of the bills fall to me, that would have been stressful, to say the least. So there was some incentive to return as quickly as possible.
Thankfully, my boss is understanding. If I need to take off early, or come in late, he takes care of me. I haven't had much need of that though. I only had one day that I couldn't bring myself to get out of bed and come to work. I do truly feel fortunate to have not suffered a more debilitating injury.
As for the hair, I'm intrigued by members like Julie Green with long hair who say that it covers up their bald patch. They shaved right across the top of my head the first night in the hospital so they could put in an external ventricular drain (EVD). I woke up the next day with somewhat of a reverse mohawk. Not a good look! So once I left the hospital, I opted to clip all of my hair to the same length to let it grow out. Anyway, is the EVD not a common practice?
Again, thanks for all of the motivating messages folks. It really makes a difference.
