Dad with breast cancer

I'm not sure where to post this, exactly.

My dad was just diagnosed with breast cancer and in the span of about a month has: received the diagnosis, had a mastectomy, found out it spread to about half the lymph nodes tested... and now is starting chemo.  

He is tough and he has my step mom.  All of us "kids" are in another state, though.  

I am awaiting the results of his genetic testing with trepidation.  I am worried about both of us.  (I just found out his sister had breast cancer, too.  I hadn't known.)  And I'm worried for my step mom, who has lost several family members in the last couple of years (parents; BIL; DIL, through divorce); this is a lot for her to deal with in a very short time.  I just lost my mom in 2011 (multiple sclerosis), watched my grandpa die in 2012 (Alzheimer's).  

My dad and were just reconnecting after many years being mostly estranged.  (I am a child of divorce.)  I am just getting to know him, trying to deal with the previous losses, etc., and was not "ready" for this to be thrown into the mix.  (Obviously, things are worse for him, no one is ever "ready" for cancer, etc.  I'm really not feeling sorry for myself, I'm just saying...  I guess...  that emotionally, this was already a time of loss for me...  and my step mom... and we're just not as strong right now, maybe, as we usually are.  I am glad that my dad doesn't hide stuff from me or sugar coat stuff, though.  Not knowing is usually way worse.)

Just throwing this out there.
