I remember being very emotional through my whole cancer,and even the first year seemed overwhelming, even with medicaton. Things are much better now. I never had raditaion but from what I read hear the people that have had it says things will get better. I am almost 3 years out from surgery and my speach is still changeing.
As far as being more emotional and crying at the drop of a hat, I think in going through what we have, and facing our fears, our mortality, our weaknesses and strengths we just can't put on the plastic face anymore. At least that is how it feels with me. I don't have the strength or desire to be the least bit superficial of phony. Life and death are just to real. No one has a guarantee for tomorrow. When I really had to face that, it changed me.
