Thanks Ceara for the reply.I don't need to read what you said about telepathy I know for a fact telepathy is a real thing,I've read my sister's mind in the past and she has read mine,we were really close at one point and just could tune in to each other from a distance and read what each other was saying/thinking.

I've also done it with other people so it is a real fear and not my imagination or thoughts due to the psychological abuse,people either know telepathy is real or they take your view and don't believe it is. either way nothing will make me agree it isn't a real phenomena cos I have had so much practice on it in the past.

I have to learn to block my thoughts so no one including my sister can read them neither is it the case she read my body language cos we weren't in the same room when this type of communication took place.

I don't know about my so called friend whether to give her the benefit of the doubt cos sometimes she'll have digs at me that feel very insulting,like she kept going on about a certain shop she goes to where the plants on sale have no labels she says they just called vegetable plants and there is no way of knowing what type of vegetable it is and the tone and mannerism she was saying it implied she was calling me a vegetable,that is emotional abuse, it was happening way before this thing with my sister so I didn't have PTSD symptoms back then.

I am not mixing with people who have that kind of humor and I'd rather be alone that have that happening cos it ****s up my self esteem and before you know it it becomes more and more frequent and the person is abusing you on a daily basis.So no I am not going to give her the benefit of the doubt.I have been badly bullied before on a daily basis not just by my sister,I attract bullies for some reason and used to put up with the less serious abuse then it would become major abuse in no time so I know what I am talking about and doing on that score.

I don't want to dismiss what you say Ceara but your advice is what is right for you but not for me cos I know different and my situation isn't exactly the same as yours.If this friend admits to being sarcastic which I 100% know she was being and apologizes for it then I know she isn't lying to me and I'll let it go but no one is ever going to pull the wool over my eyes again and get away with it thems my rules.

I am not going to be told my judgments about other people are down to my having PTSD or mental illness either that is a big No for me too and smacks of unfair prejudice.I know if my illness is affecting my judgments but other people have no way of knowing they just assume either based solely on the fact they know I've been ill or like you assume its the same for me as it is for them cos they've been ill themselves.Well your experience and mine isn't the same in this regard.I know when though,even though, I've been through the recent trauma whenever my mind is reacting as though my narc moved something in the house and I moved it myself without needing film of me doing it.
I am sorry to disagree with your advice but that is how it is for me!Thanks for the support though.
I will get CCTV for the outside of the house cos then i will feel better about using the keysafe.
I am not worried about being isolated I can make new friends if I make the effort.Though it isn't easy for me and I have never been one to have a lot of friends.
