Books that rework negative thinking into postive thinking.

Hi all , I was feeling a bit depressed (mild one ) and lacked self esteem since last November. I am not depressed anymore but something has changed since. The kind of optimism i used to have is gone.

Are there any books that can improve my self esteem and make me feel better about my life?

Like, are there any books that can provide hope about our life . Any book that can rewrite our brain into postive thinking , improving our self esteem ,can give us hope.

I have already read man's search for meaning but that did not help. I am not in search of books that promote stoicism either.

Thanks in advance
