You are def'ly not alone in this one......There are days where I feel confident and happy then one word/glance even by someone I don't know and down I go. I too cant offer any real advice I know what works for me tho. In that situation, I just try to think of a time when I had a really good time, alone a time when I truly enjoyed my own company and realize that maybe it is them not me. If they do not like me maybe it is something about them, maybe they see something in me that they wish for, just maybe they are hiding some of the things that I hide behind my mask, a mask they see as friendly/confident whatever.
