losing hope. Any book reco to help me keep going in life?

Hi so with the caption itself says pretty much about how i feel. Um im just so at my edge of hope to keep going. I'm 23F. And i lost my mom 4 years ago. Feels so alone. I don't have any other family, been living alone and working since 17. I have no friends to talk to. I have no feeling of a hope to keep going anymore, and uhm, looking for a sense of purpose, or maybe a book can help me change my mind?
