Hi, thanks for your comment/question. To note - I'm one of the current authors that cover addiction on HealthyPlace, not the original author of this article.
Before I start, if you have any suicidal thoughts, please refer to this article http://www.healthyplace.com/suicide/suicide-hotline-phone-numbers/. It contains some excellent resources.
I know that these recent examples can cause extreme shame and guilt, but it's important to remember that you're human, and we all make mistakes. I could write a book about my past incidents with alcohol and the chaos that came with it. Instead, it's better to focus on what you have control over.
My first suggestion is to consider AA. Even though you're young, there's no age limit to heavy drinking and/or alcoholism, and it can often feel comforting to know there's a support network available, even if you don't decide to attend regularly at this time.
Second, apologising helps, but changing behaviour is the best way to make amends.
Lastly, be kind to yourself. Forgive yourself. Feeling this level of regret means you're a compassionate person who cares about how others feel.
Someone once told me that if you can forgive yourself, you'll find it easier to do the same for others.
You can't change the past, but you can set a new path for your future. I wish you all the best in your journey - please come back to let us know how you're doing.
