Stress at work after maternity leave

I recently returned to work after my maternity leave, feeling excited and eager to reconnect with everyone. As a team lead, I had managed three teams and was looking forward to resuming my role. However, upon my return, I learned that the project had been thriving in my absence, and it seemed that my presence was no longer essential. Now, management is looking to reassign me to a different project.

This realization has been deeply painful and unsettling.

I poured my heart and soul into building this project and team from the ground up, making countless sacrifices—including my health and well-being—to ensure its success. After all that effort, coming back to find myself sidelined has been incredibly difficult to process. The stress and emotional toll are overwhelming, affecting not just my work but also my ability to focus on my family. I'm also deeply anxious about transitioning to a new project, fearing that I won’t perform well and that my job security might be at risk.
