If your mother is unwilling to get help, you have to decide whether to help yourself or not. Your mother isn't keeping you high, you are going to your mothers to get high. Both of you are adults and both of you have your own lives to live and obviously are not helping each other and are detrimental to each other's health! So, you have to choose and it's your choice, not something forced upon you. No one says it will be easy, "natural", pleasant or any of those things but if you can only save one life, you have to go with your own because it's the only life you have that you are in charge of.
