I just need to rant, I've holded it in way to long.

When I was born, My dad's father died, same day, just 18 minutes after I was born. My father has never liked me, mostly for this reason. He always called me a curse when growing up, and every time I do something bad he brings this up. This is really deppresing for me, I actually started believing he was right. I got teased at school, my brother's where young and told everyone. I got called a weirdo, freak, curse, and the most hurtful of all a killer. It is hard dealing with this, and it hurts for those words to come out of his mouth. I just dont know what to say to him when he brings this up, what can I say besides your hurting me saying these things to me, and that it's not my fault? I have never knew why he died, and neather does my dad, but my dad believes it my fault. I just dont know what to do, or who to talk to, something this little really triggers me, blaming his father's death on me, he's pretty much saying I killed his father cause I was born.
