36 year old meth user, can anyone help me stop?

i am a 36 year old female mother of a 16 year old girl, im in a 10 year relationship with a wonderful man, and i have a 13 year long meth addiction.
I WANT TO STOP!
i can't afford treatment, i know if i stopped using then i could afford it but stopping is kinda impossible without treatment. i don't qualify for state or county help and i can't do it on my own. my boyfriend is supporative of me seeking help and wants me to stop but doesn't know how to help me. i've tried to stop on my own but that didn't work. i know i'm an addict and i know i want to stop but the physical and mental addiction is to hard for me to beat by meself. not many people know that i use, i don't look like the typical "crankster", so its hard for me to ask around for help from friends.
if anyone has any suggestions i would appreciate them, please only serious ones.

All you need is WILL POWER. If you want to stop using drugs then stop using drugs. Mind over matter.
