OMG - how much is one person suppose to take? I have no words for you because your story is so heinous. You are an adult now, take care of yourself and YOUR family. Even if that means leaving your birth family behind. You've done your time and paid your dues girl. Make sure that YOU don't repeat the same mistakes that your family taught you. End it here and now and have a healthy family of your own. Are you in counseling? If not, I would very highly recommend finding a GOOD counselor. Also, try NA or AA. As everyone here has told me many times, let go and let God. Your mother/sisters addictions are not within your control. Take the energy that you're putting into them and put it into your OWN family. BTW - Methadone is STILL a drug. My AH was heavily addicted to that only to get clean and go to oxycontin. AH said Methadone was WORSE for him than the oxy. So don't think that your mom is technically clean, because she's not.
