This is the major problem I have when dealing with girls and finding myself going back into my own head.

If I'm not getting signs of interest ill get frustrated, go into my own head and rationalise it on something stupid such as looks. I can't deal when I'm with a friend or a group of friends and we go out and meet some girls and straight away I struggle to garner the attention or pull girls in when I speak, and then they hang off every word another friend says.

It's just something I struggle with and I guess many people do but what is the best way to stop seeking validation and attention when you struggle to get it?
