I Lack a Sense of Family With My Family

Four years ago I lost my dad and five years ago my little brother. They were all the family I needed in my life, but since they died nothing feels the same. My mother never cared for anything but herself, even after my father's death, she was only sorry for herself.
I have a crazy sister which always brought random men into our home, and two brothers that just do drugs and live like rats in their apartment, honestly I'm not even exaggerating. Their home is pure filth, a normal person wouldn't enter that place.

If I didn't meet my husband I might have just killed myself too. Because I was so blinded by their greed, selfishness and hatred that I thought it was normal.

It's messed up, I feel detached from them and it keeps me from trusting people into my life.
