Why does our thoughts push us to remove fear ?

A big hurdle or fear that I want to overcome over many years is driving. I told myself 7 years ago I'm learn driving and be independent on my own but I just never put my mind and effort into learning. I learned few times with an instructor until I had an accident which I felt embarrassed and intimidated so ever since than I just completely stopped learning driving. I'm taking this minor incident turning into a big deal in my head. But my thoughts keep nagging me to overcome the fear. Like I just feel this discomfort within myself like what are my thoughts trying to tell me. Are they just trying to push me to learn driving once again. Do I just need to face the fears once again. Sighs I want to learn because I'm trying to work on my life.
