Hi there
I have similar problems, I feel for you too. My child manipulates to get her own way and chucks things out of temper. Luckily she has lots of support from school. Can you contact your child’s school for pastoral care and counselling? I know it would depend if your child wants to engage. Also do you have support for yourself from family and friends? I’ve spoken to C.A.L.M online before, but if you google there are other helplines too. I know its not necessarily going to magic problems away but they may sign post you to people that can help. You’re not alone. Good luck.
