You’re doing everything “right”—staying active, showing up for others, pushing through—but you’re still stuck in your head. You overthink everything. You’re constantly anxious, tense, and on edge. Maybe you feel like you’re always performing—for your team, your job, your family—and you’re tired of carrying it all.
