OP
I have had a difficult teenager dd. I asked for help because I was at my wits ends but I never ever thought about throwing her out. You are lucky she complied and went to her sister. What if she got really angry and decide to sleep rough to punish you?
You could be one of those mum trailing the streets with a poster of her now.
I asked for professional help and I was told I needed help not her.
I learnt I had switch off completely when she was shouting and trying to feel compassion for her as she must have been in a lot of pain, her feelings and hormones all over the place and I was the safe punch bag to release the emotions. This was a cry for help.
I stopped retaliating and answered with kindness to her abuse. Acknowledging her feelings of anger and how could I help.
It wasn’t easy, but we seem to have come to the other side now and she’s able to articulate how she feels rather than screaming her feelings out.
You telling her to stop talking to you and following you has the opposite effect and makes her angrier in my view.
You telling her to get out is telling her you have given up on her, her own mother rejecting her.
Try to understand her feelings. Not all teenagers are the same I know but some feel “stronger” than others and don’t know how to deal with their feelings.
It is your job to teach her that. If you lose it yourself nobody is learning anything and it’s quite harmful for your relationship.
She will be grateful in the future to know that you put her feelings before yours.
Not easy I know at a conscious level. You can only acknowledge it to start with within yourself and you can see that slowly you will become detached and focus only on her emotional well being rather than yours.
And it’s so rewarding...
