When a key teammate suddenly leaves mid-project, it can definitely feel overwhelming. I've been in similar situations, and one thing that really helps is stepping back for a moment to assess what’s within my control. I prioritize tasks that need immediate attention and break them down into smaller, manageable pieces. This helps me focus on action rather than the stress itself. Communication is also key—openly discussing with the remaining team members about workload redistribution or possible external support helps ensure no one is left carrying the burden alone. Finally, I try to keep perspective by reminding myself that challenges like these are part of the process, and overcoming them often leads to growth for the whole team. It’s not easy, but staying focused on the goal and not the problem makes all the difference. How do you handle sudden setbacks like these?
