It may grow on you (sorry that was truly awful).
I have had my hair cut short several times and always hated it. I have finally learnt my lesson and am never going short again.
My dog barked at me the first time i had it cut as she didn't recognise me.
Oh and i have to say that i found it harder to do not easier. When it's long you can always tie it back.
Sorry not much help now.
