J.K. Rowling had a heartwarming response to this struggling 'Harry Potter' fan

When she's not busy hammering trolls into the ground on Twitter, J.K. Rowling likes to take time to interact with her fans.

She's previously comforted people on Mother's Day and Christmas, and reached out directly to people who tweeted at her to ask for help and advice.

And on Monday, she did it again.

It started when a Harry Potter fan tweeted to thank Rowling for her books, which she said provided an escape from her depression.
