Hey there all My biggest fear is rejection and my insecurities and because of that I don't know how to approach a girl or how to talk to them .

Whenever a girl tries to talk to me I get fumble or my brain goes foggy in sudden and also I somewhat fear girls

So please tell me how should I overcome this or I have a mental problems and please give me some tips how to approach a girl offline or online without being a weirdo .

Thanks ..
