Did Mary Lincoln need committal?

It has just struck me that whatever Mary's fault's and defects both real and exaggerated by her detractors, she more than paid for them after Lincoln's death.

Her life after the assassination seems to have been one long agony, 18 years of degradation, humiliation, pain and loneliness.

I don't believe she ever had another day of true happiness after April 14 1865. No wonder in her letters she often expressed a longing for death.
