Books on co-dependency?

one non blonde

can you suggest any books on how to deal with co-dependency? i've look through quite a few of them and feel overwhelmed with all of them. i posted about the differences in types of dependency and relationships but no one answered my post. i'm at the chapter about anger and today i thought long and hard about reasons to be angry, thinking that i really don't have any, and it was funny cause i kept repeating this song over and over again in my head, it was like my mind would not let me think about what could be causing me hidden anger if anything. it was like a barrier or something and it is scaring me now cause i don't understand why i kept doing that, like maybe blocking something that i don't even know anything about.

then i was asking about handling things in my life with the mind and behaviour of an adolescent, rebellious and defiant. i cannot find anything in this book that applies to that kind of behaviour or about filling the love tank? do you know anything about any of what i'm talking about? i'm seeing a therapist april 4th, but until then i want todo as much as i can on my own. thank you for any help you can give me, i really would appreciate it, thanks again.
