“I could feel my doubt and fear growing but I had to close my heart to those feelings”

Simplified Meaning:

When someone says they can feel doubt and fear growing inside them, it means they are starting to worry and feel unsure about something. Doubt makes us question if we can handle a situation, and fear makes us scared of what might happen. But if we give in to these feelings, they can stop us from doing what we need to do. Imagine someone getting ready to speak in front of a big crowd. At first, they might feel really nervous and question if they can do it. But instead of focusing on these nervous feelings, they decide to put them aside. They tell themselves, "I can do this," and focus on their speech instead. By choosing to ignore these negative feelings, they can stay calm and do a good job with their speech. This idea teaches us that when we feel nervous or have doubts, we can choose to not let those feelings control us. Instead, we can focus on our goals and push forward to achieve them.
