Adele has opened up about parenting, her struggle with postpartum depression and alcohol use in a new interview.

The 28-year-old singer tells Vanity Fair she felt like she had made “the worst decision” of her life after having her son, Angelo, who’s now four. She says she eventually had to spend some time alone in order to overcome her postpartum depression.

Adele also touched on cutting back on her drinking and quitting smoking. She says “having a hangover with a child is torture.” She says she used to be a “massive drinker,” but now only indulges in two glasses of wine a week.

The comments are in the December issue of Vanity Fair.

Adele wraps up a nearly year-long tour of Europe and North America on November 21.
