My absolutely absurd family.

Okay, so long story short: half of my famliy are selfish, arrogant, potheads. My mom is a great person (although she has her moments…frequently) but her family is crazy! She is the middle child of three girls. Her parents seperated when she was a teenager and it was due to my grandpa running around on my grandma… After the seperation nanna(grandma) started dating everyone! My mom was in the middle of all the crap. Her older sister lissa(I changed her name) got in a unhealthy relation ship and had a boy and girl… Girl is my age boy is younger … They turned out to be little demons!!! The other sister is linda(changed her name too) and she is dating a rag-a-muffin and is a pothead. She has one son who really is a total butt!!! My grandad just recently broke it off with the woman who he ran around with while he was with nanna. My mom is the only normal one on her side of the family! My mom got pregnant when she was 18 with me… She and my real dad are still together.. They came out with a lot of success and the rest of my family is really jealous..(im not stuck up thats just how it is) and now im leaving tomorrow to go camping in nc with my grandad, lissa, and her kids!!! Im going to go crazy! We cant have a normal thanksgiving, so how are we going to stand eachother camping?! Am I overreacting, and what can I do to set an example for my family to just be nice to oneanother?!?!
