?*Experienced Homeopaths Please* My sister needs Psychiatrist or Homeopathy

Hi, I am very much concerned about my sister, she is a mother of 2. 1 is 12 months old and the other is 2 months old.

Her background:
She was always a very mischievous, outspoken, extrovert girl. She always loved to meet people and talk and laugh loudly and she used to tease others. We are 5 siblings are we are mostly quite and we mind our own business, except her.
My parents were always very angry because of her nature and we sent her to girls hostel to get religious education. She complete high school studies there, then she came back home. She has a very bad habit to tell lie. She used to tell other girls there that she belongs to a very well off family and her step mother and step siblings torture her real mother and they have sent her here in the hostel, and we don't have any step mother or step siblings. she makes fake stories and tells other people.
She always and easily tells lie and then to make that lie a truth, she speaks even more lies.
She had a habit of staring somewhere and keep staring there for long, seems like she is thinking something. She bites her lips unknowingly and in deep thoughts to remove the dead skin from them and it looks abnormal.
She was lazy and used to do domestic chores according to her own will. When asked about completing a work she shouts back that don’t say it again and again.
Then we thought that maybe her marriage will help her, as she wanted to get married as other girls in our society have a dream. She got engaged and used to talk to her husband to be and she was happy.
Then she got married in December 2016. After that her husband and in-laws had complain that she doesn’t listen to them which she should. She used to do what she wants.

Present:
After her mother-in-law’s death her husband works in another city and she is living with us. She has some strange and weird habits. She is very much careless about her children. She has gained some weight, but she is lazy as hell, even she doesn’t go for walk in order to lose weight. At night, if she is sleeping and her children are crying for milk or anything she is always in deep sleep, she doesn’t care at all. Even me being their aunt wake up and bring milk for them specially the elder one. The younger one still needs mother milk and all she does is to put pacifier in her mouth in order to shut her.
She doesn’t seem to care why my child is crying all she says is I’ve just fed her, then she again puts pacifier. If we are sitting in a room and children are in another room and crying I will run and check why they are crying but she doesn’t even move from her sitting position. She feels it really hard to stand up when she is sitting or lying. She doesn’t care if the feeders are boiled or not. I have shouted a thousand times on her and then she does a little bit of work but we cant consider it as care, because I know ho mothers care for their children. She thinks that dressing up and cleaning the children is enough. She has had inferior complex but now she has to think about her children.
She has taken a lot of money from her husband and she told him that my sister wants the money, which I never asked for, and she bought gifts for us family member s and others with that money. She has told a lot of lies to her husband. She wastes money on useless things, gifts, dining out, etc. Her husband says that he can’t trust a single word which she says. And I wonder they have a whole life to live ahead, and her husband doesn’t trust her at all. But the irony is she doesn’t care at all. Her husband is humble but he gets angry as he sees her not listening to him or anyone. I asked her why she tells lies to her husband, she says because if I ask him something and he says no, so it is better to tell lies. It means she has to do what her hear t wants and she doesn’t care what other think. She has this permanent “I don’t care” attitude.
She laughs on useless things, talks non sense. And there are a lot of minor details about her.
Homeopathy has helped me in controlling thoughts, so I thought I should post her issue here.
Experts are requested to suggest what should I do? Take her to a Psychiatrist or homeopathic remedies will help her.
Thank you,
