1. Accept the emotional state: It is normal to acknowledge and accept that one cannot immediately forget their current emotional state. Don't rush to force yourself to forget, but give yourself time and space to slowly adapt and heal.
2. Shift attention and interest: Look for new hobbies or activities to enrich your life, such as learning new skills, participating in sports, traveling, or getting involved in work. All of these can help you shift your attention away from past memories and reduce your longing for her.
3. Establish a support system: Maintain close contact with family and friends, and share your feelings. Their support and understanding will be an important force for you to get through this period. At the same time, you can also consider seeking the help of a professional psychological counselor to better handle your emotional issues through professional guidance.
