Failure

How do you deal with failure? Do you feel ashamed? Angry? Sad? I'm interested in knowing how others process failure. I am very sensitive and tend to internalize feelings of shame for not being able to succeed at a task. I've often had "help" with feeling ashamed but the feelings are my responsibility. How do you view yourself when you have failed at something? For me it's been a struggle to feel my value or worth. I think I'm improving in this area but it seems i shift back and forth between self esteem and shame. I am interested in your comments.
