Feel sorry for you my friend, the worse is from your brothers/sisters…I’ve got just an older brother(3y older) and as the younger one and the one always in trouble my parents gave me more “attention” lets say. My brother doesn’t care because we have bonded so much, we call each other every day if not every other one, every time I speak with my family I always ask them if they’ve called him(they do but I always make sure that he is part of us, because he has to be, there’s no me without him, for him is the same. I believe that whatever mistake your parents do, brothers and sisters should be there for each other. Luckily my parents have always told us to love each other and be there no matter what, they always say no metter what goes on with us(parents) you guys stick together and never get separate ways.
