If you take part in this study, you will get a random assignment (like a coin flip) to receive either a healthy lifestyle behavior program or your usual medical care. We will schedule you to complete an in-person study visit when you begin the study and again about 3 months later. At each visit, you will:

• Answer questions about your symptoms, emotions, health behaviors, and health history
• Complete a 6-minute walk test
• Have your height, weight, and bood pressure measured
• Provide a urine sample, if you are a person who could become pregnant
• Have a blood draw, to measure your cholesterol levels and your hemoglobin A1C (average blood sugar level)

If you are assigned to the healthy lifestyle program, we will also ask you to:

• Complete 8 one-hour sessions with a study therapist over video (Zoom®) over the course of 10 to 12 weeks
• Wear a wireless activity tracker (Garmin®) that we will provide you
• Measure your blood pressure and weigh yourself using Bluetooth-enabled devices (Qardio®) provided by the study team
