Leadership comes with pressures that are different in kind from other kinds of work stress. When you're responsible for a team or an organization, the weight of decisions, the isolation that often comes with the role, and the difficulty of showing any uncertainty can compound in ways that are hard to talk about with the very people you're leading.
Therapy offers a thinking space that isn't subject to office politics or the expectation that you should have it together. You can work through the specific stressors of your role, including the relational dynamics, the self-doubt, and the impact your work is having on other areas of your life. People in leadership under sustained pressure deserve support too, and getting it tends to make you more effective, not less.
