Hi penny...
I've never been a group person either...especially when it comes to reaching out...like you I feel exposed...I think for me it comes from trust issues...I've been attending some meetings, and I dread when they ask me to share...I know you don't have to but at some point you should....I'm going to meetings to try and overcome this...and help me grow more...I'm just doing baby steps....I think the more we do it maybe the more comfortable we may feel....I guess time will tell!!
