Glad to talk to you.
In short, each and every member of my family has no doubts that X is mentally unstable, except her! I shall provide you with some information about her. After reading the symptoms, kindly, I wish to ask you about the possible disorder(s) you may think she has. But the matter is as follows: she believes that she is an average person thereby rejecting seeking medical advice. If I get to know her disorder(s), then I may have something to do.
It is not a medical advice; it is a matter of help: if you state, for example, that those are symptoms of autism, and I believe you immediately and ask her to take medications to ease autism(a prescription is needed as you know),then this is medical advice! If you state that those symptoms may be related to autism and I evaluate your opinion myself, then this is just a matter of opinion and guess.
Information and symptoms:
Has problems and disagreements with many relatives; has terminated many friendships; she used to trust those friends extremely and used to tell them her own secrets but again and again, she says I found out my friend was not faithful; she has spoken to many relatives with swear words criticizing them and insulting them, and terminating the relationship after the event immediately; she was unable to become a wife again and again as follows:
she ended her previous marriage in divorce; the second relation ended after several month as they were getting to know each other and did not get married; the third (current) relation is being a mother for a six-month infant and leaving him for his father to take care of him and going back to our family house; she always thinks that people are conspirator against her, even her closest family members; no matter what you do, she will never trust you.
-Most important things to know:
she sometimes freaks out and screams loudly in a terrifying way, and sometimes hits her own face while doing so; she is really confident and believes she is always right even if all of us disagree with her; she is strong not sensitive at all; she thinks this way: if my baby is beautiful, then because he is my son, but if he is ugly, it is because he is his father’s son (I am the cause of good things and others cause bad things); she feels the desire to break our religious rules and looks for freedom (we are Muslims); she once did not care about her infant because he looks like her dad and she had problems with him at that time; she just got her degree as a dentist with a GPA of 3.2/5.0; she once said I am a dentist and smart and thus mentally stable; she is really aggressive so that no one dares to criticize her or suggest something to her.
I hope that you provide concise answers so that it becomes much easier for the community to read each and every response you provide!
