Maybe let her have a little independance she feels she is growing up and maybe feels you are trying to stop her, my daughter is 11 as well and yes hormones i think are starting to kick in and things can be a big deal at the time little things that werent so bad a couple of months ago!
I think the trick is learning where to let go and let them fend a little more for themselves and when you know you are really needed, i sit my daughter down or try to every now and then to see how she has been feeling especially if she has had a bad week at school or things like that we talk about how she feels what she thinks she should do and things like that, she still feels heard but the tantrums and things like that i tend to let her have them a little because their minds are changing the way they think is becoming more complex and they still dont completely understand that yet it takes time for them to learn as well and maybe a little space from us.
