DARTMOUTH, N.S. Grade 12 student Gabrielle Caya says some days are harder than others and weeks feel like they re blending together, as she learns from home during Nova Scotia s third wave of the pandemic. Just yesterday and the day before, this is the third day now where I m just so tired and drained, the 18-year-old explains. I have no motivation to do anything. Caya misses interacting with classmates and teachers in-person, or visiting friends and family. The founder of Children First Canada, a charitable organization that strives to improve the health and well-being of children and youth across the country, is sounding the alarm on mental health challenges young people are facing during the pandemic.
