Suggest me a book which helps me find that spark in me again which I’ve lost.

I'm in my mid 20s – at the worst place since an year. Lost the person I love, lonely, don't feel like doing anything, asocial – you get an idea. But sadly, this wasn't me. I always aspired to be something and there used to be a Naruto like energy, a spark to make an impact in this world using my actions. Now, It feels like I've lost it all – most alarmingly, I've lost the confidence in myself that I can make an impact. I'm a shadow of who I was. Anyways, if you've felt the same and if any book (Fiction or Non-Fiction) helped you regain your spark; do let me know. I don't want to be this way forever. Thanks in advance.
