In 2011, Bryn started taking Prozac to improve his communication and lower his anxiety. It worked well at first, and his doctors increased the dosage. But one day in 2013, Bryn became very ill. He struggled to convey his distress. Courtesy Millie Thomas
Two years after he became ill, Bryn's teacher read on Wikipedia about a condition that can be brought about by antipsychotic or antidepressant medication. His Prozac dosage was cut back, and Bryn improved. Courtesy Millie Thomas
