Its hard to say if its PTSD, no one here has the power to give you advice on this, especially me.
First I do not know you and I do not know the events that have unfolded at your home. Secondly, I and no one here has the background to give you any kind of formal treatment - whether its in advice or mental coordination.
My only suggestion is for you to go see a real professional psychiatrist (do not go see a medical doctor).
