What to do

What or how do you work past an issue that makes you uncomfortable. It sounds trivial but for the life of me I cannot seem to, or want to, write scenes that can affect a childs' relationship with his/her parent. I can envision it but I'm unable to put it to paper. I've known several people that have had a poor relationship with theirs but mine was never like that. Its like a stumbling block for when I have to write it. It's essential to the story so there's no way for me to skirt around the issue. Unless the parent is a total bitch (which she is not) I cannot write it.

Suggestions would be helpful. No I cannot fake the relationship in this sense.
