I know it feels like a big thing to take that first step and it's because you've tried to retain that hair as much as you can and it feels weird getting rid of it but look at it this way, imagine not having that insecure feeling anymore, imagine not having that problem in your mind, imagine feeling like you did before you discovered you were losing hair. Shave it, let it go, hair's gone and all your problems along with it. I got to the point where I had worried and stressed over my hair so much during my twenties that I just reached that boiling point and then just stopped caring.
