What should I do? I just discovered I have a half-brother I never knew about.
How do you feel about having a half-brother?
I'm angry that my dad didn't tell me about him.
I can see where that would be shocking and uncomfortable for you. Can you talk to your father about this and learn more about your half-brother?
My father is a deadbeat and I haven't seen him since I was an infant. I don't care about my half-brother or my father. Actually I do care about my half-brother because he is half my genes and I feel the need to hurt him.
It's understandable that you are hurt and in shock about having a half-brother you never knew about. You should make small attempts to get to know your brother, rather than feel anger toward him.
