Hai madam, psychiatrist prescribes medicine and psychologist gives counselling (talk therapy) and there are several types in it. I think i answered your question.
1. Family itself is a organisation, so one gets disturbed and others also get disturbed, so it is understandable everyone gets disturbed.
2. Better to ask a professional rather than worrying about it allow it to become worse.
Next Steps
Meet someone who is expert in family and adolescent psychology , because it includes the development of your family.
Meet someone who understand your value system, rules and norms and doesn't speak western philosophy.
Health Tips
Don't make trial and error experiments madam. Meet clincial psychologist inperson.
All my very best for your family and you. Things will be better soon.
