You made the move and chucked the rug, and that really was the hardest part, though it might not feel like it at the moment.
Try to look on your new hairstyle as just that: a new cutting-edge, very sleek and noticable hairstyle. Don't worry about feeling exposed: enjoy it!

I know it's easier said than done, but the feeling of freedom will come, and the feeling of being different will fade, to be replaced by a desire to be noticed for your bald head!
