Nicole Spencer, 24, a medical student who suffers from Postural Orthostatic Tachycardia Syndrome (POTS), checks her social networks before going to sleep, at her apartment in Syracuse, New York, U.S. May 7, 2022. For Spencer, apps like Instagram and TikTok provide a bridge to meeting new friends because their conditions rapidly deplete their energy and can make it painful to walk. "I don’t go out. I don’t get as much social time and I don’t make as many friends" Spencer said. REUTERS/Magali Druscovich SEARCH "DRUSCOVICH HEALTH SOCIAL MEDIA" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.
