My mother and stepfather died with no will?

my mother died on 11/19/06 because of that it was my responsiblity to look after my step-father due to health issues. He gave me power attorney to take care of things on his behalf...he has no children just me, he changed me to sole beneficary on his life insurance in place of my mom...he elected not to include any of his brothers and sisters. Unfortunately the day he was supposed to talk to a lawyer about making a will he ped away 2months after my mom.I got a lawyer and was bonded and now i am the adminstrator of my mothers' estate & my step-fathers' estate i understand that although the deed and property is in my mothers name the lawyer has the house as part of my step-father estate because my mom ped 1st so it automatically went to him. I am so stressed out because i am all alone in this ..i feel like my aunt & uncles are going to benefit from all the work i'm doing making sure everything is alright..when he wasn't close with them & b/c iam just his stepson i'm nobody :(
