M20 & F23 close siblings

r/

Lately I’ve been trying to help my big sister who’s been suffering from mental health issues. Mostly anxiety and depression, she goes to professional too. She seems to just feel really safe being close to me and likes to spend time together. I don’t mind and cuddling with her is sweet. Kinda similar to how we were growing up, we’ve even slept in the same bed.
How could I help her better? Anyone have similar experiences? Any thoughts or advice? I’m open to chat more

TL;DR: I’m pretty close with my sister and asking for thoughts
