I totlaly understand that. I true do but, you have a good mind and soul so you need to share it a little. You don't have to shoot all the way out. Think baby steps. :-)
I use to too. I use to be only open to my closest friends which were like two people and one of them(love her though) eventually made me voice out my opinions in a trick like way. God I hated it but I'm glad she did so or I would still be a clamped shell...Will you pop out of your shell once in a while?...for me? lol
