How do I recover when I'm the one everyone leans on at work?

You built the systems that keep everyone at work feeling cared for, and somewhere in that you became the person all of it leans on. You catch the falls. But no one built a system to catch you, and after years, that gap has hollowed you out. The care you give is real and good. But you are not a bottomless resource, and pretending to be one is not strength, it is a slow way of disappearing. The people who lean on you are not cruel; they simply cannot see a weight you have gotten too good at hiding. Begin by making your limits visible. Say no to one thing. Ask for support out loud, even though your role is to give it. You would never build a workplace system with no maintenance and no backup. Stop running yourself that way. You are worth the same care you design for everyone else.
