Effie, I wish you good luck in what you are doing. Most of what you are scared of is only imagined. Yes, some will laugh, some will be offended that you chose to tell them ( you busted their image of you), some will be down right hostile too.
But, you are going to find those special people who care and will remain by your side no matter what. Appreciate them, let them know what they mean to you. It will be hard and easy and all points in between, but YOU can do this for YOU!
