David Foster Wallace § Personal life
Wallace struggled with depression, alcoholism, drug addiction, and
suicidal ideation, and was repeatedly hospitalized for
psychiatric care.
[52] In 2008, his father said that Wallace had suffered from
major depressive disorder for more than 20 years, and that
antidepressant medication had allowed him to be productive.
[53] In 1989, Wallace spent four weeks at
McLean Hospital, a
psychiatric institute in
Belmont, Massachusetts, affiliated with
Harvard Medical School, where he completed a drug and alcohol
detoxification program; he later said his time there changed his life.

In the early 1990s, Wallace dated writer
Mary Karr. In 2012, Karr described his earlier behavior toward her as obsessive and volatile, alleging that he once threw a coffee table at her and once physically forced her out of a car, leaving her to walk home.
[54][55] In 2018, Karr said that the account of Wallace's alleged abuse in D.T. Max's biography of him was "about 2% of what happened"; she claimed that Wallace had kicked her, climbed up the side of her house at night, followed her five-year-old son home from school, and attempted to buy a gun to kill her ex-husband.
[56][57][58] In 2015, Karr said that Wallace was violent toward other women he dated,
[59] and in 2018, she said that several women, including former students of Wallace, contacted her to share their alleged physical and emotional abuse by Wallace.
