It's natural to feel bad when you fail or get rejected. However, it's important to understand that failure and rejection are a part of life, and they can be opportunities for growth and learning. Instead of beating yourself up, try to reframe your perspective and focus on what you can learn from the experience. Talking to a therapist can also be helpful in processing these feelings and developing coping strategies. Remember, it's okay to feel bad, but it's important to take care of yourself and bounce back stronger.
