This is an issue that can cause problems in a family and increase anxiety for everyone in it. There is often a lot of pain involed for everyone, including the person who's abusing alcohol
Accusing someone of being a drunk or of having a drinking problem is the wrong way to go. When drunk, people will own up to lots of things, but when sober, they may well deny any problem exists. That's how addiction works. So accusing someone just doesn't work. Don't waste your time taking that tactic.
When a family member's behavior causes problems for the family, then it (the family) can address the issue of the behavior (and state that alcohol is present in each incident.) Alcohol is the substance that's being abused. There is such a thing as alcoholic binge drinking.
It's up to your sister to own the behavior and to address its cause and correction, meaning that where her responsibility lies. Helping her to face her responsibility and helping her to find solutions is not always easy, but it can best be done when she is sober. Depending on what kind of things she is doing, you and your family can get further help from the police, a lawyer, addiction center, mental health clinic, etc.
A family has the right and obligation to establish boundaries and to establish limits. It's difficult for just one family member to change anything though.
If you are experiencing panic attacks because of the family situation, then perhaps you can talk this over with your parents, school counsellor (if you are still in school) or family doctor. Have you told your parents how this affects you?
Have you taken the anxiety test?
