hello marty and welcome. i am sorry your post got overlooked. i am sorry that you are going through this with your mom. i can understand your frustration, worry, & concern.it is very hard to watch someone we love in addiction.
mixing xanax with methadone is very dangerous. both are respiratory and central nervous system
depressants. she could very well be using heroin too.
methadone takes a while to get off of. it has to be tapered.
she really should be still attending
AA/NA, celebrate recovery, church something to help her.
you and your dad should go to al-anon. it is a support group for the loved ones of addicts.
trying to talk with an addict about their addiction most time turns into a shouting match.
you can't reason with them when they are using. they aren't thinking straight.
how old are you? you are worried about your mom and your little sister. of course you are you love them. your dad should be the one to talk with your mom about the fact that it isn't safe to
leave your sister with her. addicts will lie, manipulate and try to shift blame for their use on others.
your dad needs to take control of the money so your mom doesn't have it to buy more drugs.
how old is your mom?
