I started in this group 6yrs ago. I was at my wits end with SD. We had a few rough years. When I joined this group it was going on 3yrs of horrible times. Shes 13 now. We bump heads like any mother/daughter do at this age. She tells me about her problems with school and friends and boys. We joke, we gossip etc. She has no contact with her bio mom at this point. She has a lot of anger towards her..just wanted to let you know that it may seem like theres no end to this. But there is.  I put my foot down, became the wife and step mother from hell. I refused to be disrespected.  I refused to allow my bio daughter to be disrespected. My bio is 8 now. And I think oh ok. It's an 8 year old thing. It wasnt personal. Because she acts dramatic and insane just like her sister. It was magnified with SD because I took it personal.  I wish you all well.
