The goal of this clinical trial is to learn which types of telehealth-based treatments best fit the needs of caregivers of people with rare neurogenetic conditions. The main questions it plans to answer are: * Which telehealth support programs best meet the needs of rare disorder caregivers? * How can individuals be matched to support programs that are right for them? What aspects of an individual (e.g., demographics, mental health symptoms, family characteristics, lifestyle) predict whether treatment will be a good fit? * Does peer-to-peer coaching help improve patients' experiences during telehealth treatment? Participants will be asked to complete a 12-week treatment program, which may include self-guided resources, individual therapies, group therapies, and/or peer-to-peer coaching. Before, during, and after treatment, participants will complete questionnaires to help researchers understand their experiences, symptoms, and impressions of their support program. Questionnaires will include both standard forms (administered up to 5 times throughout the study) and brief snapshot surveys that participants complete on their smartphones up to 3 times per day. Some participants will be assigned to a waitlist control, which means that they will provide data while they are not yet completing a support program. These participants will be assigned to a support program in the next treatment phase.
