I might have more to say later, but for now, read my responses on this thread, they seem on point.
I think you might be like me, in that shame comes easily to you. Such a person might seem like they are ranting about their past but, if investigated, are on a deeper level blaming
themselves for not being worthy of love. In that case, the subtle or not-so-subtle moralism of "victim" and "responsibility" and "excuses" just runs too close to the nerve of self-blame so another approach may be more useful, at least at the point in the process you're at right now.
