you are absolutely not the only one!!! As part of my studies last semester, I had to do some work on politics and economics.... and I felt physically and mentally ill the whole time. I have never been so depressed and close to wanting life to just end as I did back then. It has made me realise that whatever I do after studying, I never ever want to get involved in something political. I agree that it must be really hard for those who go into power hopeful of making helpful changes who after a while must feel like they are just getting nowhere. I really don't believe modern politics or economics has much to commend it, but there are no solutions at present that people are willing to take up. I agree with Sam2 that if you are feeling particularly sensitive to current issues, best to put your head down and just deal with life as it is at the moment. I suspect that one day it will all come to a crisis and then some things will change, but until then we just have to cope.
