In order for someone to feel less vulnerable, you should try to get through your current emotional state and start to feel more positive about yourself. Doing anything that improves the state of your mental health, such as self care/self help, taking up sports and physical activity or spending your time in a positive group of supportive people, will help your confidence to grow and make you feel less vulnerable. Social workers, teachers and healthcare professionals need to create care plans that mitigate the vulnerabilities of people in their charge, for example, vulnerable children that need additional safeguards to be put in place for extra protection.
