Leo is super secretive. Your identity and ego are closely bounded by your emotional state, which means any threat to your reputation can be a source of stress. Controlling your emotions is a big ask of you.
Stress can flare up within you and can create self-doubt. You may lack the ability to go with the flow and accept the fact that you cannot control everyone. To reduce stress, you need to learn to live in the moment instead of trying to control every little aspect of your life.
