Hello st.bipolar!
Yes, it is a result of my illness that I changed my place. I have to say before that during my last assistance I suffered from a big "high" and I noticed I lost concentration.(My english fails me sometimes to express everything right;it was not only loosing concentration;I think you all know what I mean-everything went pink...! - most of the time I`m very good at hiding this fact when it happens..) Well a heart Op lasts very long and you simply have to work accurate all over the time. Of course my chief took notice and we had a loooong talk. In my case, he was very understanding and explained that he doesn`t want to miss me (We work 10 years together;that`s almost like a marriage -without sex of course-

) but the has to take care for the safety of his patients during the operation.
I understand this and I do not feel discriminated. Unless, my own heart bleeds.
He was also asking me if he should inform my other colleagues. I thought about this very long and then agreed:
First because: They already might wonder why I work in a different place (or behave strange sometimes) and it`s better they know the truth before some rumors get started.
Second because: When my boss informs my colleagues everyone of them knows that he stands behinds me.
Their reaction was positive in most cases. (there are always some stupid ones around but I`ve chosen to concentrate on the intelligent ones..

)
I can very much understand that your girlfriend is reluctant in telling about it. I for myself (and well:
to myself ) tried to hide it for a long time. You must be very sure for yourself inside before you do it because you never know what will happen then.
To me, it`s always a bit like getting naked before others, although I consider myself as very frank and open. (Sometimes tooo frank or open, I suppose..)

But this is still my most vulnerable point.
But it came to the point for me facing the fact that I cannot help people in that kind of mood and that was particulary the reason for me why I always wanted to work as a nurse.
Life is funny sometimes. I got understanding from where I didn`t expect it (at work) and experienced rejection where I never thought it could ever happen! (In friendship or whatever they call it)
