How to deal with toxic mother??
My mother is toxic af. She does not know how to talk to us… She even hurt us emotionally n mentally. Plays victim all the time. She is a bp patient so she hide her every mistake by saying ohh i am a bp patient ye voo. I hate her or i can say i hate to know that i am related to a person like her.
She has no emotions she is compltly selfish person.She is a housewife bt she has no interest in house chores.
Most of my anxiety is becoz of her…
She actully discriminate btw me n my younger brother so much.
He get everything he wants bt us get only wht our parents wants…gussa ata hai mujhe my mother did not even cook our fav food but my borther get all the things his fav food etc.
