Here's the back story
When I was little I was a daddys girl and when I was 4 my parents split up. Then my did vanshed and I then didn't see him till he showed up on my 9th birthday and after that I started to get to know my family and well I never thought they like me much as a child but no it is just ovious they blank me at family events and make really horrible comments. I just don't understand why they don't like me I want to be part of the family but I don't think I can take any more of it. I do still care for them all.
What I'm trying to ask is
-why doesn't my famiy like me
-what can I do to change it

I think your Parents have/had some problems, you may be in the middle, People can get so consumed with their lives they lose track of what's important.
They may have used you against the other, or even suspect. Try not to worry about it, do things to better yourself/career. Can they use your help?
