I don't think she could face any sort of real closure. Look at how she carried on after Art... I don't think she's either intellectually or emotionally able to face reality. Psychological counseling can only be a Band-Aid because her personality has been set now for 40-some years. It's not like she's going to change.
Now, she could act like she's seeking closure. That will be some funny shit.
Personalities are not set in stone, growth and change are always possible... when and if one is motivated. If her public persona and statements on her show are to be believed, she's just not motivated or self-aware enough to be willing to do the hard work to grow. However, we don't know what's going on in her private life, so who knows?
Curious as we all are, it's better for her and she's better off NOT to be so much in public right now, imho.
