When you have BPD, your sense of self is typically unstable. Sometimes you may feel good about yourself, but other times you hate yourself, or even view yourself as evil. You probably don’t have a clear idea of who you are or what you want in life. As a result, you may frequently change jobs, friends, lovers, religion, values, goals, or even sexual identity.HelpGuide.org
