1) The most important thing you can do to help your daughter is to help yourself. You will play a significant role in influencing who she becomes whether you want to or not. Understanding how your father’s past contributed to him becoming who he was and how your past has lead you down the path you have walked can give you a great deal of the wisdom needed to help raise your daughter and steer her down the right paths. We have far less control over what we communicate to each other than our conscious minds are aware of. The best way to communicate the right things to your daughter is to understand them yourself.

2) A good psychotherapist can be an enormous help in understanding yourself. Unfortunately, not all of them are good, so don’t feel like you can’t doctor shop when looking for a good therapist.

3) We all live our lives in what can be called the “theater of the mind”. In that theater you are the writer, set designer, protagonist, and you create the entire cast. The “self” you believe yourself to be is not who you truly are, but merely the main character created by the mind in this drama of you and it goes by the handle of “ego”. The mind creates the ego, and then identifies with it as self, forgetting that it is something it invented. This is often disparaged in spiritual circles, but I believe it is a necessary thing for us to experience life in a close and personal way (which you have). However, when you come to understand this, it becomes easier to not take this ego so personally, and to look at it with the mind with some degree of objectivity.
Since you are on a site called “Tiny Buddha” I would recommend reading up on the Buddha’s concept of “Anatta” or no-self. It is subtle, and I am not sure anyone truly understands it, but contemplating it does help the mind see beyond its fixation of the ego as “self”. I doubt you would lose the ego, but you might develop the ability to look inward (insight) with a better degree of objectivity. The mind is fully capable of examining its own creation with some degree of objectivity, it just needs to see it as such first. Also, key here is looking inward with an eye toward understand the ego (and the theater for that matter) rather than judging and condemning. The more we cast judgment on something, the more the mind paints it as we see it rather then what it is.
