ive had a child with a narcissist

Hi! I have a child with what i believe to be an undiagnosed narcissist/sociopath. i have read tons on the subject and even got so desperate i had a counselling session over the phone and was advised to discuss things with a dr as my childs safety and well being are important and it is better safe than sorry. after a couple more months i again felt i had reached my wits end and took up thiis advice. the first dr i discussed it with was ok and gave me another appointment with the clinics 'mental health expert' this i attended and while i was giving him the back ground on why i believed my partner to be narcissistic i was telling him of the dangerous situations she had put my son in. he called social services and our conversation ended. i was asked to leave the room and he took out what i believe were my partners health records. when i went back into the room he apologised and said had he known all this...........gesturing to the paperwork still strewn all over the table he would never have made the phone call but there was nothing he could do now it was in social services hands and that i should keep quiet and let the drs deal with it.
i got a call from social services within a week and had to be quite covert about it as my partner was around. and after a discussion they decided the only action they would take was to get an information sharing thing going with my sons school so if i wasnt here for any reason (my partner frequently threatens to kick me out of the house im paying for) to protect him then they would have a line of defence if abuse is occurring. thing is how can i protect my son if a diagnosis my take years if at all and if i try to turn to anyone i am told i have no buissiness making such claims of narcism as it hasnt been diagnosed when im living with and seeing all the signs and syptoms on a daily basis and i cant discuss it with anyone outside proffesionals because if word gets back to my partner i have spoken out she will end the (relationship) no doubt stop me seeing my son or turn him against me or use him as a pawn for her own needs. im totally lost and confused. my partners grandma was a diagnosed psychopath but only after she attacked her own children with a knife and pretty much every member of her family has a mental health issue of varying degrees my partner has also been diagnosed with depression.please god help or give some advice.
