I think what we experience in therapy is what we need to experience. When we can drag out that "baggage" and look at it and work through the feelings about it, it can cease to be baggage that we have to drag around. It can become a little memory box that we place on a shelf instead; something to take out and look at if we want to versus something that is always there like a heavy backpack strapped to our back to carry around. I think the strong feelings you are having might indicate you still have some grieving to do.

I hope you are talking to your therapist about your feelings after/between sessions.
