Dear Lemminaid,
Well done for posting on this forum, and recognising that you and your sister deserve support. It is a really good idea to find out what is available in your local services, which you can do using the service finder map on Adam’s home page.
For specialist, confidential emotional support and practical advice you can call the NACOA helpline on 0800 358 3456. NACOA is the national association for children of alcoholics and their helpline is a safe place where you can talk about things that are going on for you and how you are feeling.
Very best wishes,
Clara x
