Children of Addicted Parents and People

heya,
things have got worse over the last couple of days! I'm trying to ignore things & that but it's difficult when we're leaving together. I just don't know what to do anymore. I've tried speaking to my family but they have all said just ignore her as she is only going to pull you down. The only person i seem to be able to talk to is my aunty Shiela (who is my mums sister) but as i mentioned before my mum is adopted and as always been jealous of her sister. My aunty does really try to help but my mum doesn't even want to know her, and she defiantly wont take any advice from her or let her help us out .My aunty and me are so close but there is no way i could stay with her as she cannot afford me & she has two young children so its out of order as she has her own life to live. I really don't know what to do. Things are getting worse and i can only see two ways out, me being arrested again or her trying to commit suicide and obviously no one wants any of those to happen but i just cant see any other way out. It feels like we're going round in a circle but its getting darker but there is no way we can get back out - do you understand? please give me some advice or contact details of someone who can help please... x
