I'm sorry you felt you needed to escape this way. I hope you do stay safe. ( I also hope you get sick as a dog to help you remember that acting out is not good for you!)
You haven't failed anyone, except maybe yourself. Since you're posting in the negative, it sounds like you do care that you've done this.
Remember, alcohol is a depressant, so you are more likely to feel worse about yourself for a while because of it. Stay safe Tomorrow is another day, and you can make good decisions then.
