Also...one more thing :) I wasn't talking about
your mother and her speaking to you that way. I was talking about
other people, and different ways of seeing their behaviour
. I'm sorry if my post sounded different to what I actually meant, sometimes it's hard to get across what I mean successfully, or I think it might come across the wrong way.
I hope that you have been able to have a relationship with family members on a level which is comfortable for you and safe, sometimes people change over time, sometimes there are other people as well, that people may be able to look to for support, understanding and kindness. Sometimes also people say things in haste when they don't really mean it, or have other things going on, which they might be angry about.
I can't pretend to know what the reasons are and it doesn't mean I accept it, just that I hope that your confidence grows :)
