1st of all, let me say I am sorry for your loss(es).

To me, the therapist isn't saying she can't help you so much as she has done what she can. This doesn't sound bad at all. She said you are grieving. And that sounds accurate from what you said.

A therapist can give you help & advise you, but grieving is something personal that you have to go through when you lose loved ones.

I think it is a sign to you that you are strong and able. That is when a therapist says something like this. She has faith that you are going to be okay in time.

That's the way I would take it. As a good thing.
