Books to cope with suicide grief/loss?

I (f, 22) lost my brother (m, 20) to suicide in July. I've always been a big reader, and right now it feels like the only thing I can do. I've read It's ok That You're not ok, Martyr!, Cutting for Stone, and The Covenant of Water in the last couple of months, and I'm looking for more books that are either non-fiction about coping with trauma and suicide loss or psychology, biographies on that topic, or just fiction about grief and loss. TIA.
