It is like a wound that needs time to heal. If you are experiencing these feelings, it is important to reach out for support, whether it's from friends, family, or a therapist. It is not always easy to navigate love, and heartbreak can be incredibly painful. It is okay to feel those emotions, and it is not a sign of weakness.
