As a college student, Megan Beaulieu first noticed her smile faltering and her arms growing weak, which she chalked up to stress and exhaustion. Within weeks, her symptoms had worsened to the point that she could no longer lift her hands to wash her hair—a progression that led to her diagnosis of myasthenia gravis, a rare autoimmune neuromuscular disease. Since then, she has taken to TikTok to share her journey. We spoke with Beaulieu, who now works as a project manager at a construction firm, about living with myasthenia gravis, her decision to use social media to educate and inspire others with the condition, and how she learned to advocate for herself before advocating for others.
