Hi there
Thanks for sending your letter to me. From what you say in your letter life at home with your step dad is really difficult. What your step dad is doing is wrong.
Well done for trying to talk to your mum about how you feel, but I am concerned that your mum isn’t listening to your worries.
You say in your letter that you want to run away. Running away is not a good idea. It will only place you in danger and there are safe ways of resolving your worries believe it or not.
First of all you must go back to your mum and tell her again the effect that your step dad's comments are having on you. No one has the right to call you names. If you feel this is too difficult try writing it in a letter or email your mum.
If you can't do either of these things is there another adult you could talk to about this? This could be a relative or a teacher at school or college.
You could also come and talk to a ChildLine counsellor online in 1-2-1 or phone 0800 1111.
Have a look at what other young people in similar situations have done and check the ChildLine message boards. You could even put up a post yourself for advice. I hope this helps.
Take care
Sam
