In the face of being rejected, adopting a mindset and actions of revenge is usually not the best way to solve the problem. A healthy approach should focus on self-growth and emotional recovery. Here are a few suggestions to help you get out of the emotional low and face the future with a positive attitude:

1. Accept reality and allow yourself to grieve.
- It is normal to feel lost, sad, or angry when a relationship ends. Give yourself some time and space to experience these emotions, but also gradually learn to let go.
- You can release negative emotions by crying, writing in a journal, or talking to a trusted friend.

2. Focus on personal growth
- Use this experience as an opportunity for self-improvement. Whether it's learning new skills, enhancing your appearance, or strengthening your physique, investing in yourself is always a good idea.
- Work hard or study to become better, which not only helps to shift your focus but also boosts your confidence.

3. Expand Social Circle
- Don't isolate yourself. Try participating in new activities or joining interest groups; meeting new friends can bring freshness and may open up new possibilities.
- Being with positive and optimistic people can inspire you to see the beautiful side of life.

4. Maintain a positive attitude
- Although it may be hard to imagine now, time will heal all wounds. Maintaining an optimistic attitude is crucial for overcoming difficult times.
- Practice gratitude by finding time each day to think about the things in life you are grateful for; this helps cultivate a more positive worldview.

5. Give each other some distance
- Trying to contact each other immediately after a breakup may hinder your recovery process. Give each other enough space so that both parties have the chance to calm down and move forward.

6. Seek professional help
- If you find it difficult to cope with emotional issues on your own, consider seeking help from a psychologist. Professionals can provide effective strategies to deal with complex emotional states.

Remember, true "revenge" is not about making the other party regret, but about living your best self. When you become more confident, happy, and successful, that is the most powerful response to past hurts. Always remember that everyone encounters all kinds of people in their lives; some are just passing travelers, and what you need to do is keep moving forward and find the happiness that truly belongs to you.
