The welfare room and nurse's surgery are in Q staircase, behind Third Court. Students can drop in here to speak with the College Nurse, Ana, for any sort of physical or mental ailment. Ana is happy to see students for an informal chat, and you'll also have a College Tutor who can help you to access the right kind of further support when appropriate. All students are also registerd with a local GP.
Another source of welfare support is the College Chaplain, who is happy to discuss any matter, be it pastoral, religious or random, and remember that the College porters are available 24-7 and are all first aid trained too.
