Having to talk within a group who are all listening to me

I am self conscious and on the shy side so having to do ANY talking within a group makes me tense and drains my energy very quickly. If only a couple of people by me are listening, I am ok with that...but to have everyone’s eyes and ears turned my way...oh my gosh.

I try to avoid situations like this as much as I can. I do not like attention drawn to me and I sort of feel like crawling into a hole.
