Disability Resource Centre
Many people aren't aware that long-term mental illness is a form of disability. The Disability Resource Centre (DRC) can provide support to students with long-standing mental illnesses including, but not limited to, depression, schizophrenia and anxiety disorder.
The Disability Resource Centre can help you make alternative arrangements for exams, help you with your application for Disabled Student Allowance (for UK students), or help you find other sources of funding. They can also help with study skills sessions, and can act as a liaison between you and your academic supervisors.
You may get in touch with the DRC before you arrive, or at any point during your studies at Cambridge. The first thing you will have to do is fill in the online Student Information Form (here). This will help the DRC find you a suitable adviser for you, and help them to assess your needs. They will then be able to offer you practical advice and support, and can help in developing useful strategies to manage your mental illness.
