Why is that our siblings can hardly become our best friends and we find comfort in others around us than at home?

I wonder this a lot. Im the baby of the family. My oldest brother was 18 years older than me, my sister is 17 years older than me and my other brother is 12 years older.

My oldest brother and I finally got close 4 months before he died. After Christmas my sister announced she has cancer. We are slowly getting closer. My other brother and i were the closest and now don't even talk.
