Hello
Thank you for contacting Sam. It sounds as though your mum is very lucky to have you around. Clearly caring and supporting her is becoming too hard for you to manage alone.
It's understandable that you don’t want to tell her because you think it might upset her. I am going to suggest to you to be brave and think about speaking to both your mum and dad.
They need to know and understand that you cannot do this alone and without help. If you don't feel you can do this right now, there maybe another adult that you feel you could share this with? Like a family friend, teacher or mum's health support worker if she has one?
There are lots of young carers and there is support. So first of all have a look at the ChildLine message boards there is a board for young carers to support one another.
Next if you think it would help come and talk to a ChildLine counsellor about this by having a 1-2-1 chat or calling on 0800 1111.
Have a look also at www.nhs.uk/CarersDirect CarersDirect or www.youngcarer.com both of these web sites provide information support and contacts for young carers.
Take care
Sam
