Dear Q,
Crying and feeling guilty are normal, and finding whatever family you have dysfuntional is normal too, in this world of dying and living. Here is a thought my sister just shared with me, and I hope it may become true for you and for all of us: from Rabi`a al-Adawiyya: We are eating the bread of this world and doing the work of that world.
Hugs,
Nouce
