Methamphetamine addict having difficulties with suspicious mom

[tweak123]

swim's mom has been getting suspicious of her use. she gets frequent nosebleeds, her mother makes comments about her having dark circles under her eyes, she's lost 40 lbs in the past few months..and the kicker is swims mother's brother used to be a cokehead. so..she knows the symptoms. swim is considering telling her mother but first of all she doesn't want to stop..secondly she doesnt want to disappoint her..thirdly she doesnt want to go to rehab (not only because it sucks but also the fact that its the 2nd semester of her sr year in high school and shes almost done)..and doesnt want her mother to worry about her when she goes off to college. would it be wise to just fess up and get it out in the open or do you think swim should just cut down for a while...and let it be?
