Are they cyber-stalkers like the police have said, bored or crazy...?

Long story short I answered a question here not being into the show Spashley- surprisingly if you change a main character's last name you have the loved one who "was fighting for her life" - the plot line remained the same for them and in the mean time my life was really going all wrong and I was fighting for my family and losing everything- are people really that shallow that they would make stuff up and how sick do you have to be to enjoy someone else's suffering that you maintain the same lies and lines even though you are caught? Worse yet I suffered a brain injury- what happened to people today? how weak do you have to be to find enjoyment out of another's pain? How shallow do you have to be to hear the truth and fear from a person and mae things up for sympathy? More over how sad is the existance of a person who does this? Is this not past attention desperado and into psychotic or socioschitzo disorder? The person even made up a multitude of names and id's - it has me wondering if one person does not truely believe they are infact all these people- though I am pissed how can I tell the authorities this person needs psychological help?
