Gift ideas?

I'm looking for a gift for my sister, she's recently become a mom of 2, she has a toddler and a newborn but suffering from depression. For the passed couple of years shes been struggling with energy and motivation, she seems to have given up her studies, all her hobbies, rarely goes out anymore because of anxiety and low self esteem and spends most of her free time zoned out on her phone or binge watching Netflix till 2-3am. She says she wants to change, loose all the weight she's put on over the years, wants to put in the energy to live a more positive and outgoing life but she burns herself out quickly and goes back. Shes even called herself a slug not long ago.

I want to find her a Christmas gift that will help her start taking care of herself again, I know a gift won't cure her mental problems but she never spends money on herself so she doesn't have much.

Any ideas of any self care/lifestyle gifts for someone trying to reinvent themselves?
