Hey Tigger,
I don't think anyone thinks you did the wrong thing, you have to be strong for your daughter and for yourself. No one should be scared in their own home.
Like I said, if it were me and I had to chuck out my sister, no one could console me, I'd feel awful even if I knew I'd done the right thing. So even tho you'll most not likely feel any better.... carry on as you were, you've yourself and your daughter to look after and keep your chin up. Thoughts are with you xx
