My sister is suffering from depression and my family did the most clown thing possible

My sister (cousin) is suffering from depression and mental health issues, she is in high school so I believe it's because of pressure of board exams and maybe something which happened to her in school (relationship or some jealousy which is common during teenage years)

she just told us she is suffering from depression and didn't revealed any reason and we didn't force her either

my family is now going to do a hawan at the house and restrict her from eating onion, garlic and non vegetarian food for next few days instead of taking her to a therapist and giving her proper medication

I don't fucking understand how a planet moving from point A to point B in it's orbit or restricting someone from eating certain kinds of foods/dishes or putting a bunch of flammable things in a flame can resolve someone's mental health issues 🤦‍♂️

awareness around mental health is a joke in this country
