Hi pink pink,
CANT TAKE NO MORE is right. There are ways of you speaking to people, to let it all out, which may help you. The Icarus Trust is an organisation which provides you with a Family Friend – someone who has been in a similar situation, who you can speak to. They all have experience with addiction in the family. You can contact them on info@icarustrust.org or see their website http://www.icarustrust.org.
Best of luck!
