Leo is super secretive. Your identity and ego are closely wrapped up with your emotional state, which means any threat to your reputation can be a source of stress. Controlling your emotions is a big ask for you.
Stress might bubble up for you and may generate self-doubts. You might lack the ability to go with the flow and accept the fact that you cannot control everyone. To get relieved from stress, you need to learn to live in the moment instead of trying to control every little aspect of your life.
