Christine, this is a good list of why you SI. Work on your depression and your self loathing. How is your depression and self loathing today related to your past? What has caused (from the past) how you are today? Decreasing your depression and self loathing will decrease/stop your need to SI.

Working on not feeling alone will also help you to decrease/stop your SI. Many people with these issues are afraid to let people close. Working on your fears and your skills will help you to allow people closer to you. These skills are healthy boundaries (because unhealthy boundaries don't allow you to protect yourself), social skills, expressing your repressed feelings in therapy to decrease your anxiety, improving your self worth because low self worth causes a person to keep others away so that they can't see the real you. (Improving self worth involves discovering why it is low in the first place. What messages did you receive while growing up about your worth?)

Did the mental health professionals say that they are going to take away your SI?
