Daily struggles

I did get back to work after 3 1/2 weeks. But on Feb. 4th I was pulled from service again because apparently I got Carpel tunnel in the accident. The Dr. believes it was the I grabbed the "oh sh#t" handle when the bus was going over. I can see how it happened. I've ben off work since. I had my surgery on the 24th of Feb. I was pretty ticked off for a couple weeks after being pulled from service and it didn't help that my bestest little buddy died the day before. It took a couple of weeks to calm down. Since then I've become very much at peace with things and I'm worried that when I go back to work that all those people I work with and for are going to put me right back where I was emotionally. I'm not sure how to avoid them. I can keep to myself pretty much but then there are those who insist on being in your 'stuff'. Since the accident I haven't cared much what comes out of my mouth. I think it's the 'I could've died' thing that makes me do that.  Well, along with the anger of "why me?"
I have my follow up on the 23rd. So, until then, I'll be fine.
