Am i a failure at life?

I am 21 years old, i graduated from a midwifery degree last year and i am struggling to find a job. I can get job interviews (i have had a total of three job interviews), but i never seem to be able to get a job. Everyone around me are able to get jobs, majority of my batch mates are employed, it seems i'm the only left behind, im never good enough. i feel sick to the stomach. what should i do to make myself stand out more? I feel like a failure at life.
