ILikepeace,
There is a lot of hope and help for you.
When we are really little, we pick up on what our parents are doing, how they react to stuff, how they treat other people, and how much they like themselves.
So you can really be copying your dad even if you do not like what he did.
But you do not have to stay that way. Not at all.
You can change alot - so that your dad's life will not be your life.
You posted here, so you must want to change. And you can.
Alateen is a great program. It is just like Al-anon which is a program a lot of us really enjoy. You can find a local meeting on the internet. Ask a teacher or minister or another adult that you trust, and they can help you too.
Take care of yourself.
