Mental Health

Being a student during a pandemic is challenging and might be very overwhelming. If you need support during times of struggle, reach out to friends, family, or faculty you trust. The student union at UdS also offers a counseling service that you may contact. You do not have to go through this alone! If for whatever reason (e.g. a personal emergency) you cannot attend the lectures or deliver your work in time, please let us know and we will make appropriate arrangements.
