Can I change my feeling of being worthless to everyone?

It sounds like you may be struggling with depression. Depression can make you feel overwhelmed and paralyzed to change. I would suggest that you connect with a provider who can help you get to the root of where the worthlessness is coming from and help you develop a plan for recovery. In the meantime, small steps can go a long way. Self-care interventions such as journaling your feelings, mindfulness meditation, and regular exercise are all helpful to reconnecting with the present moment and gaining internal motivation. Focusing on one day at a time and bringing your thoughts back to the present can also be beneficial. There is hope!
