Bonnie,
Hello and Welcome to HealingWell.
I know exactly how you feel out in a social situation.
Temporary fluctuations in our self confidence are common, they happen to most of us. Try self talk, tell yourself you are fine. Tell yourself you can go to the party or what ever event you are fearing and that you will be ok. When you begin to feel bad, such as being at a party with a whole lot of people you don't know, stop the "stinkin thinkin" and take a deep breath. Tell your self you are ok, many of the people at the party maybe feel the same way you do.
Take a break and step outside for a bit of fresh aid an remember you are every bit as bright, witty and intelligent as the rest of the party guests.
You can do this, I have great faith that you have come so far that a few more steps will get you to where you want to be.
Again a Warm Welcome to you.
Gentle Hugs
Kitt
