Does anyone else have issues with guilt or self pity during the healing process?

I haven't worked in 6 months. My job requires a good deal of information processing and decision making, which are obviously not my strong suit right now.

I feel like I'm letting people down both in my family situation, my friends, and my job. Right now I just feel like a burden to everyone.

The way this PCS dominates your life just sucks. It's the only thing on my mind most of the time. I feel like family and friends just get tired of me not showing any real progress. Probably just me, not them. Not having a real strong grip on emotions dealing with this. Staying positive wears me out.

Is it just me or antbody else deal with these feelings?
