Journaling Intervention for Temporomandibular Disorder (TMD) and Chronic Overlapping Pain

The goal of this clinical trial is to learn whether a 2-week gratitude journaling activity is feasible and acceptable for individuals with Temporomandibular Disorder (TMD) and chronic overlapping pain. The study will also look at whether this activity is helpful in reducing pain and how much it interferes with daily life. The primary aims of this study are to: * Assess whether individuals with TMD and chronic overlapping pain are able to complete the 2-week gratitude journaling activity as planned (feasibility). * Evaluate how acceptable participants find the gratitude journaling activity (acceptability). The secondary aim of this study is to: • Explore whether the gratitude journaling activity reduces pain and its impact on daily life, compared to a general wellness journaling activity. Participants will: * Attend two in-person visits to complete questionnaires and take part in tests that measure how sensitive they are to pressure and heat. * Complete a 2-week journaling activity at home, writing in their journal on three days of their choice per week.
