How can I escape the abuse of my father when he is drunk ?

What I would suggest is call someone or lock yourself in your room. I personally found it easier to call someone about my dad so it's an idea.

Please reach out to people around you. Counsellors at school, teachers, the police. Whether or not you're underage is irrelevant, your father has no right to treat you this way. If you're under 18, you can be placed with friends or family members in order to keep you safe. If you're over 18, there are Victim Advocates at police stations that can help you find affordable housing and employment. Please keep yourself safe!

To escape the abuse of your father when he is drunk, you should really call either 911 (if it is serious and you are scared for your life or being hurt) or the Domestic Violence Hotline and talk to someone to help you through the time. You should find help immediately at the least.

You need to report this, you need to be safe. Nothing you do can stop it. Only think that will stop it will be him stop drinking

Try to lock yourself in somewhere away from him, or stay away as much as possible. You can even try Child Abuse hotlines if it gets hard for you. Always keep someone in the know about what's happening to you.

Go to another family members house if there is one near by, stay with a friend who knows about the things that you deal with in that situation, or if you really need to, call 911 and explain what is going on.

Get help. I mean it. If your father abuses you, you need to get help. Stay away from him while he is drunk and/or abusive.

Speak out about this. You need to talk to a teacher you can trust, a family member, friends, your doctor or the police. Don't keep this inside yourself, don't be alone with it, someone else needs to know so they can help you. You don't deserve the abuse.

I would recommend contacting local authorities, Child Protective Services, or other related agencies to insure your safety and the safety of others in the household.

That is such a tough situation to be in. I would say that above all else, your safety is of the utmost importance. Do all you can to try and physically remove yourself from the danger, whether it be going to another person's house you feel is safe (a relative, friend, etc.) if you are in immediate danger. You could also call Emergency services if you feel that it warrants an intervention. In the long term, you could access resources or services that can assist you in getting you out of the environment. You shouldn't have to tolerate feeling unsafe in your own house.
