Nicole Spencer, 24, a medical student who suffers from Postural Orthostatic Tachycardia Syndrome (POTS), studies for her final exams, at the library in Upstate Medical University, in Syracuse, New York, U.S. May 7, 2022. Spencer's plan is to become a pediatrician and work with children and teens who must also manage chronic conditions. "Through all of the experiences that I've had, through being sick myself or seeing my friends go through much more challenging illnesses… if I could make one kid feel a little less alone, that would be my dream," she said.
