Hello there
Thanks for your letter. It can be really scary knowing people you care about are hurting themselves in this way. People who take drugs can sometimes find it very hard to stop and can sometimes really be struggling with difficult feelings themselves. Have you ever talked to your mum or stepdad about how you feel? Sometimes adults think they can keep things from their children, sometimes not realising that children and young people are cleverer than they give them credit for!
You did the right thing to talk to your big brother about this, and I think he has given you some really good advice. People you can trust could be a teacher, a school counsellor, a school nurse, a youth worker or even your GP. Talking to them and getting help wouldn't necessarily mean that you would have to go into care. Social Services work very hard to try to keep families together because they know that most of the time that is the best thing for everyone in the family. They would only put people in care if they felt that they would be in danger if they stayed at home. When parents use drugs it doesn't always mean they are bad parents - it can just mean that they need help to stop using drugs and help to deal with whatever is making them take drugs. Social Services can work with parents around this and be around to make sure that you are still taken care of properly and that you are safe.
It's okay to need some time to think about all of this and it's okay if you need to talk about this a bit more. You are more than welcome to come and talk to a ChildLine counsellor online through 1-2-1 chat or you can call free on 0800 1111.
Take care
Sam
