You should see a bone doctor and get some x-rays; you may have scoliosis (curvature of the spine). A chiropractor can help a little, but it sounds to me like you have scoliosis that started when you were about 10 and has gotten worse over time. It usually starts during puberty for a lot of girls.
There are treatments for it, but you need to get them now, before you're full grown. Your mum is way out of line for blaming you. She needs to get you to a doctor, and soon!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
