If you are seeking more information about a possible disability, please consider the following:
Start by engaging with at least one of the many offerings available through the Student Wellness Center. They can meet with you for a wellness check-in and guide you in developing stress-reduction techniques (including skills for combating test anxiety), strategies for sustaining attention and focus, and methods of slowing down or reducing racing/distracting thoughts as just a few examples.
In addition, consider connecting with the Tucker Center, an inclusive, multifaith resource that promotes reflection, dialogue, relationship-building, understanding across identities, and intentional engagement among all Dartmouth community members. Confidential pastoral counseling is also available through Tucker.
Dartmouth's Counseling Center offers an online, mental health self-screening tool and higlights a variety of mobile apps and other resources to enhance wellbeing. You can also contact the Counseling Center if you think you need to be screened for attention-deficit disorder. (Keep in mind that a screening will require multiple appointments, likely over the course of a couple of months.)
Moreover, the Counseling Center and UWill teletherapy are key avenues for support with symptoms of anxiety, depression, and other mental health concerns. If you engage in regular therapy with the Counseling Center (or work long-term with a private mental health professional), you and your provider may determine that you should consider applying for SAS services (in which case your provider can submit documentation to SAS on your behalf).
You can find additional wellness resources on Dartmouth's Mental Health and Wellbeing page.
