Very wise, godsgirl, that you've picked up on the googling problem! A lot of stuff is old on there & is not relevant to your situation.
There are many others on here with a her2 diagnosis & treatment for this is pretty good now, so you will feel better once this is all in place.
There is the 'hows everyone doing' thread on thus board, on ''going through treatment' you will find the relevant threads for your situation.
do take care
