Yes, my T says this to me periodically. I run the spectrum of feeling validated/supported to feeling like she is trying to pacify me or something. I think that has more to do with how I am feeling than what is actually going on that constitutes "a lot".

Sometimes it takes her saying that several times about whatever it is I'm going through before I accept that maybe what I'm feeling is appropriate given what I am going through at the moment. Maybe in those situations it's more about saying it's ok to feel whatever I'm feeling because of what I am experiencing rather than about the quantity of things I'm experiencing.
