If your teen is reluctant to go to counseling, it might be wise to introduce them to a potential therapist or counselor before any problems worsen. You can also set the example for them by going to therapy yourself, or perhaps take them along for family therapy and express that it’s to help you and that you’d appreciate their support.
Another option is to give your teenager complete trust and ownership over their personal therapy. Express to them that you do not have any expectations or requirements for them to attend therapy, and that it’s entirely up to them how regularly they attend.
