I've beaten this drum until it's broken, but I'll keep recommending Coda by Si Spurrier and Matias Beraga until everyone reads it. Visually, it's one of the most gorgeous comics ever produced (yes, ever). But within the pages you find a story filled with heart. To me it's about living with someone with mental illness, about supporting someone without trying to 'fix' them. Hell, I'm going to reread it myself!
