This time last year, Stephanie Johnson was miserable.
She was in her third year teaching special education at a junior high school in Lindon, Utah, about 40 minutes south of Salt Lake City.
On the outside it looked like she was doing great. Her classes ran smoothly, students loved her, parents loved her, but like many special education teachers, inside she felt as though she was drowning.
She said she thought about leaving all the time: "I don't know how to describe it, it's just so much work. I just feel like I cannot do it."
