Looking for book recommendations on BPD or generally just about navigating emotions.

Not looking for books along the lines of “I hate you, don’t leave me” (it’s slightly triggering), but more looking for books that are a bit more positive. I don’t need to know anymore about what I’m doing that is extreme, it puts me in this guilt mode that I really just can’t handle anymore guilt.

So, self helpish type books, if there are any suggestions I would really appreciate it.
