<human>: Seeing as how this community as helped a lot of individuals with problems, I've finally decided to cave and post.  I need help and any recommendations on how to build a strong relationship with my younger brother.  A little insight about my situation:

I'm in my 20's and have a younger brother.  Our family has had problems, and I took out a lot of frustrations on my brother both physically and verbally.  Most of it was unwarranted and it kills me to have put him through it.  Even if I did have a "good reason" I most likely went WAY overboard with the abuse.  We don't have a lot in common but I want to start spending quality time and build a relationship with him.  I feel with all I've put him through there's a line that kind of separates us and is difficult to get over.  It's hard for me to forgive myself so I can only imagine how hard it would be for him to forgive me.  How can I be a good brother and friend?

Could you distill the essence of the text into 1-3 sentences?
<bot>: It hurts me to have potentially ruined my brother's life and perspective by abuse.  I want to be better to him, and be not only a good brother but a friend as well.  What can I do?
