You won 't be able to identify that after the first 4-5 sessions but you should progressively be able to look forward to that part of your week where the therapist and you meet. If you do have the good luck of having a house-call therapist, you may want to designate that time as the caregiver's alone time or book reading, or visiting friends time. Sometimes the stress of adjusting to life changes may require family therapy for the couple or all family members. Everyone has feelings and sometimes we are afraid of hurting each other by sharing our feelings. The secret is, that we feel much better when there is not a lot of things being stuffed.
Therapists help people get out what needs to be gotten out and helps start healing or reconnecting.
Sometimes look at issues and solve problems. The therapeutic relationship is intimacy of a different kind. It is also helping of a different kind. It is almost like a good steak, you know it when you experience it. My wish would be that you would feel relief very soon after beginning and that your family would be able to interact in an honest and healthy manner pretty quickly.
