Her happiness was purpose of my life and now that she has lost faith in me...I don't have any sense of purpose...then what is the point of this life?

My dear friend, I hear the depth of your pain and the heaviness that comes with feeling like the purpose you held onto so dearly has slipped away. It's understandable to feel lost and questioning the point of life when something that brought you so much meaning is no longer there. It's natural to grieve the loss of what once gave you purpose, and it's okay to feel the weight of this emptiness. Remember that your worth and existence are not defined solely by someone else's faith in you, as challenging as that may feel right now. Your value goes beyond any one person or relationship, and it's important to hold onto that truth as you navigate this difficult time. From a Buddhist perspective, impermanence is a fundamental truth of life. Relationships, emotions, and circumstances are all subject to change, and clinging too tightly to any one thing can lead to suffering. It may be an opportunity for you to explore the concept of non-attachment and finding a sense of inner peace and purpose that isn't reliant on external validation. This can be a journey of self-discovery and self-love, allowing you to find a deeper connection to your own intrinsic value and purpose beyond the roles we play in others' lives. From a psychological viewpoint, it's important to acknowledge and process your feelings of loss and grief. Allow yourself the space to mourn the shift in your life and the change in your sense of purpose. Seek support from trusted friends, family, or a therapist who can help you navigate these complex emotions and provide you with tools to rebuild your sense of purpose and self-worth. Remember that your worth is inherent and not dependent on external factors. In moving forward, consider exploring activities and hobbies that bring you joy and fulfillment independent of others' expectations. Reflect on your values, passions, and strengths to reconnect with what truly brings you happiness and purpose. Engaging in self-care practices, setting small achievable goals, and seeking professional guidance can all be steps towards rediscovering your sense of purpose and meaning in life. You are not alone in this journey, and with time and patience, you can create a new sense of purpose that aligns with your authentic self.
