I was in the hairdressers last weekend and they had a copy of September's Psychologies magazine and there was a large section on Mothers and Daughters.
I didn't get time to read it in the hairdressers so I went out and bought it and it is really interesting.
The article has question/answer type sections with an analysis of how your relationship with your mother has shaped you.
There are sections on-
How our Mothers make us who we are
Understanding Toxic Mothers
Dealing with your Mother as an adult.
To be honest, I wouldn't have thought about buying it before but it has lots of interesting interviews and articles about getting through difficult times and really good ones about starting afresh and changing your life for the better.
