If you just try to do this on your own, the chances of failing are greater.
You need treatment- now- Doctor, Detox, counseling, naraon, etc....
If you do not have insurance, call salvation army and/or look up community programs that can help you for low to no cost.
also, if you get on the Methadone, or sobox program, it is expensive- from 400.00 a month and up at county clinics. You will also be addicted, and still a slave. This does work well for some, but your addiction has only been 2 years, so I think your changes are good of not using these options- but I am no doctor, and cannot say what is right for you.
Your sister does not deserve to be your mother, policing your money, and you will beg her to give it to you, and that will put her through a lot of crap.
I think that your heart is in the right place, and you really do realize what this is doing to yourself, and others in your life, and you are reaching out for help here.
I only hope you get the help you need- pulling for you
