Yes, go to the interview! Lots of jobs are "learn as you go", and companies want those jobs filled by people with the right attitude, with a willingness to learn to do the job right, with a sense of responsibility... to name just a FEW qualities that they may value in you...!
Go get a great job!
Loving yourself is an act of will. It doesn't just happen, you have to choose it.
