I'm finding this the hardest thing to cope with - feeling invisible.

Normally I'm a socially outgoing person so it is not due to being shy or introverted.

But I continue to have situations where I feel like I am not there. I recently attended a wedding and in the greeting line the greeter (who I know very well), did not greet me. There has never been any hard feelings with this person or anything. I found it very odd, he greeted the person in front of me and behind me and I stood there feeling embarrassed. I finally said hi and tried not to get in a tizz over it. I was actually in a great mood, it was a gorgeous sunny day and I was wearing a dress that I felt like a knockout in. But then...

Then at the exact same wedding it happened again. There was a circle of people I was standing in the midst of and an introduction of the groom's father was being made by one of my friends. I was the only person in the group she did not introduce to him. I felt as if I was having a panic attack. She has been friends with me for decades and I was standing right next to her. I almost cried as I felt I was not included. I was too stunned to introduce myself. I looked at my husband helplessly hoping he noticed and would say something, but alas he did not.

When the group broke up I told my husband I want to go home. I explained to him that this happened two times in the last half hour and I feel ill. I reminded him of other instances where the same thing happened. I am not coping with this at all. I feel inadequate and rejected which is worsening my depression.

Has anyone else felt this way? What could be happening to cause this?
