I don't want anything to do with my parents
Did something happen between all of you?
My family never understood me and I can't fully trust them.
Family can be difficult as is dealing with them. Just because you were born into a family doesn't mean you have be with them for the rest of your life. You can cut toxic people out of your life even if they are family.
I'm going tell you nice try and my case is special, because I'm the chosen one.
That's fair if you believe that your case is special, but it could always be beneficial to try staying close to family. There are a lot of benefits to working things out with those that you were born with and have known for your entire life, and the attempt may be well worth it in the end.
