Hi Youngpo, glad you're here
If you've been reading around the forum, you'll see a lot of advice to take care of you. Sometimes that can be read as not caring about the alcoholic, but it's not true. I became unable to help anyone, including myself, by focusing all my attention on the alcoholic. By turning the focus back on me - the only person I can control - I have changed my life for the better. I am no good to anyone else if I am not taking care of me.
Read the stickys here, educate yourself on the disease, try Al-Anon and anything that will give you face to face support, post here. You are not alone in this - by reaching out you are making a good start.
Take care and keep posting!
