now what?

so...gbf has cancer. possibly lung cancer which is one of the most insidious. he has a consult with a pulmonologist today and a biopsy will probably be scheduled for next week. i am hoping that he is able to schedule it on his husbands(they were married in california during the brief time it was legal)day off. i will go with him if he cant, but i dread being a witness to this. ultimately, i know i will be strong enough to handle it, but when i contemplate it, i cant imagine how i will.
