CT Scan showed liver and bone mets -- what comes next?

Well, can't believe I'm really here.  I feel like I'd finally gotten my feet back under me and started to trust that between the surgery, chemo, rads, and Stage 1 diagnosis the odds were in my favor that I wouldn't be needing this thread (well, at least not THIS soon!).  But as we all know, cancer is a crapshoot, and someone has to be on the "bad side" of those favorable Stage I statistics, so here I am! 

Sorry for the angst....just needed to vent a little before I actually asked for some help from everyone here.  Just almost at the 4 year NED mark, but recently I started having some steadily worsening pain in my shoulder and in my right lower ribcage when I inhaled deeply or laughed.  It was pretty well controlled with massive doses of Advil, but I when I mentioned it at my regular med onc checkup last Weds., the NP said to let her know if it persisted or got worse.  Well, it did so...right before I had to hit the road for Parent's Weekend at my daughter's college, so I called and left a message to that effect at the onc's office.  While I was on the road, the nurse called to say my onc wanted me to go to the ER to rule out a blood clot from my Tamoxifen.

The ER did a CT scan -- no blood clot, but did show what the radiologist interpreted as likely liver and skeletal mets.   I called the on-call doc at my onc's office, who said to call the triage nurse and drop off the CT film on Monday.  Just got back from doing that, so back in the waiting pool.   So now, while I wait for the doc to call me, I am trying to get an idea of what would come next as far as possible tests/procedures, etc., and a general idea of the time frame involved to come up with a treatment plan.  Main reason for wanting to know all this is to figure out when we'll know enough to pinpoint a good time to tell the kiddos -- the daughter in college is a freshman and is struggling right now, so timing is kind of a key issue.  Ideally we could wait until she's finished with 1st semester and home for Winter break (Dec. 14), but for all I know I may be deep into some kind of treatment long before then.  Just have no idea what to expect, and that's really bothering me right now more than the actual recurrence.  Bizarre, I know, but I'm a planner by nature, and what kills me is not being able to make even a rudimentary plan about all this. 

So can any of you lovely ladies who have been down this road give me an idea as to what the possible next steps would be?  THanks so much!!!
