My sister has been very moddy and detached to our family and her friends. Not as social as before, gets worried about the smallest thing, feels demotivated, has been suffering academically even though she is doing well in her tutoring classes. I want her to approach a doctor for her mental health or atleast talk to a psychologist but she is very worried. She is 20. Anything that would help her and feel less anxious in visiting a doctor?
