Rejection can be a difficult and painful experience. It can make you feel like you're not good enough or that you've failed in some way. However, it's important to remember that rejection is a natural part of life and everyone experiences it at some point.

One way to cope with rejection is to build up your immunity. This can be done through repeated exposure to rejection until you're able to normalize the experience. This means putting yourself out there and taking risks even if there's a chance you may be rejected. Over time, you'll become more resilient and better equipped to handle rejection when it comes your way.

It's also important to remember that rejection doesn't define you as a person. Just because someone or something doesn't work out doesn't mean you're not deserving of love, success, or happiness. Keep striving towards your goals and don't let rejection hold you back. In the end, it's often the mistakes and failures that lead to the greatest successes.
