Monica: what the therapist suggested was... awful. There are 'non-invasive' ways to deal with trauma but confronting perpetrators may actually re-traumatize someone, if their PTSD or other condition is severe... but it's something that ought to be a person's choice to confront/not confront, not professional advice.
I hope your sister is doing well. I've worked with clients who missed their opportunity to work on relationship with their deceased family members... we worked intrapsychically (internal family) because we each internalize a bit of our family in us and work from the inside. Worked well... it's a lifetime healing process but they felt relief.
Actually, in modern techniques you wouldn't even need to talk through trauma or think too much about it, much less confront head on...
