That voice questioning your abilities is loud, but it's not always telling you the truth. You have more capability than you think.
Self-doubt is that voice that questions your abilities, worth, and decisions. It whispers, "You're not good enough," "You'll fail," or "Everyone will figure out you're a fraud." Self-doubt and low self-esteem often go together. When you repeatedly question your abilities or worth, it can become difficult to trust yourself. Everyone experiences self-doubt sometimes. The difference is: some manage it, others let it paralyze them. Self-doubt is changeable through awareness, evidence, and compassion.
