This update isn't that entertaining.

I asked my dad about. He denied vehemently that he ever asked to have a dna test, and he doesn't believe that my sister and I are not his. My siblings and him think my mom made that up to depict him in a bad light. He neither confirmed nor denied the cheating allegations, however, which I guess he does think my mom cheated.

On the other hand, I got into a huge fight with my mother because she tried to forbid me from seeing my brothers, calling them "Talibans" which made me angry. I got kicked out and she said she doesn't want to see me this summer, so I guess I'll be couch surfing.

Anyway, I'm fine and going back to my apartment.

Thank you for everyone's help and comments.
