Love this!
I'm glad you found us because there are many wonderful, caring people here who truly understand how you're feeling. Before I found this site, I felt guilty, embarrassed, ashamed because I wasn't sure I loved my difficult children. I was emotionally drained. I felt like a wrung out dishrag, thrown on the floor, being trampled on daily by my difficult children.
I hope you stick around and give us some background information about your daughter. While we're not able to diagnose, we can share what worked and what didn't work for us, and hopefully some of it will help you. As we always say, take what works, discard the rest. We won't be offended!
Thinking of you today... SFR
