Hey stayfaded, I'm so sorry you are going through a rough time and hope things get better for you. I'm sorry I've only read this page of comments (my phone is shite), but ahh at least you can talk to your Mom about your problem? Maybe if you did go home again for a while, and tried again to get clean at your home it would be easier than doing it alone?
Also, can you go to any treatment places either where you currently live or back home? It would be great if you could have a proper sit down, face to face and let her know how serious you are. Maybe she is avoiding how serious it is and being in-denial about it herself? If possible, could you start therapy and get her to go along and support you? I really think being at your home would help you recover.
Your situation sounds really tough, we are alike both struggling with heroin and benzos. My parents don't have a clue though and I don't see them, not even for Xmas anymore

. They drove me nuts but I miss them. Family is so important. I really think that being around your family would help, and then you can go back to our friends and personal life as a sort of reward to yourself when you're recovered? I thought the same as you, but being alone has just made it so much worse. I had no idea how low I could get. I'm disgusted and shocked at it, and have nobody to keep me grounded on any level.
