I can provide some general information on the topic.
Psychotherapists, like any professionals, are trained to approach their clients without preconceived judgments or assumptions. They do not assess someone's mental stability based on hobbies or interests like knitting. Engaging in knitting or any other creative activity can be therapeutic for some individuals and can promote relaxation, mindfulness, and a sense of accomplishment.
In psychotherapy, mental stability is assessed based on a comprehensive evaluation of various factors, including emotional well-being, coping skills, cognitive functioning, interpersonal relationships, and overall life functioning. Hobbies and interests, such as knitting, may be discussed as part of a person's life and interests, but they would not be used as a sole indicator of mental stability.
Psychotherapists focus on understanding their clients' thoughts, feelings, behaviors, and life experiences to help them address challenges and improve their mental and emotional well-being. They take a holistic and non-judgmental approach to support their clients on their unique journeys to personal growth and self-discovery.
