little bit of a rant

This is a little bit of a rant. I apologize now. When I was a baby my biological mother put me up for adoption (I wouldn't change anything) when she was 16. From what I understand my biological grandparents pushed her to put me up for adoption due to being done raising kids or something like that (I really don't know why). Then a little over a year after I was born she had another baby (she kept that baby) (this rant has nothing to with my sibling). Well now my biological aunt's son and his girlfriend (they are like 16). EVERYone is SUPER supportive; even my biological grandmother.
