What a beautifully written post - ample enough for me to reply after 2 years of dedicated reading. The funny thing is you do have the strength, you understand that there are so few of 'you' around. Who would take your place? Would they express the empathy that you would, well, probably they would - you and your colleagues are professionals after all. But you'll never find that personal responsibility to the cause, trust me I know from a previous life. Abstraction between your working and personal live as well as enjoyment and celebration of your own life will see you through.
