I'm thinking of after 25 years my family has been ripped apart right before the holidays
What makes you think your family has been ripped apart?
I wasn't invited to any family parties, I guess they hate me.
You should reach out to various family members to understand what is going on for the holidays instead of assuming the worst.
I just know they don't want me around. They don't want to talk to me. I'm going to get into a fight with my father on his birthday.
Picking a fight with your father on their birthday will only make things worse. If you are this upset then you clearly care about being a part of your family. Just try reaching out and see what happens before doing something drastic.
