A painful run yesterday and after running 23km in hot and humid weather I started to really think can I possibly add 20km to this?

So...

I know that this blog was supposed to be about my road to the marathon, but today's entry is not really about running--more like my lack of running these days.  At the moment I just feel so overwhelmed, useless, and all round tired (emotionally and mentally more than physically).  I haven't slept more than two nights in my own bed since July 29th and won't sleep in my own bed again until August 25th.  My diet is thrown off and I can't eat where or when I want.  Am just worried about if I will actually fulfil my goal and my dream at this point.  Agh am way too emotional.
