Hello Nadia,
Welcome to the recovery forum. A very sad fact is that it is impossible to force an addict to get help. Until they decide for themselves, there is nothing you can do to make them quit. I expect you have let your mother know how you feel about her drinking, and that is all you can really do. You are wise to think of detox, especially since she is combining drugs with alcohol. When she does decide to quit, she should be medically supervised. We can help you find detox centers in your area when she's ready. In an emergency situation, just take her to the local hospital emergency room. It will not be the first detox they have had to handle.
Now about you! Have you tried to find alanon or alateen meetings in your area? Dealing with another persons drunkeness can be a very lonely and isolating experience. You are not alone! And going to meetings can help you to cope with the sadness of it all.
Please keep posting! We care.
Hugs,
Smoke
