Idk who my parents are

Idk who my parents are. My real mom didn’t want my sis me I when we were born so she gave us away she only cared about drugs and sex. So we never met our dads either. Till this day I feel like a piece of me is missing not knowing where I’m from and not having a family I wish things were more easier then it looks. Our adopted parents abused us for many years and dcf took us. Way back in 2011 just to be in foster care.
