theres a lot of things yu can do to overcome this anxiety.. and im sure lots of people wil reply to this message,
a few pointers i think will help yu..
create a new persona - if you call yourself ryan flowers and yu chat up a girl and she turns yu down. who cares, ryan flowers doesnt care !
have a name that is an instant convo starter... such as mine.. jude fox... to girls realising that is my name they wil instantly start singing the song 'hey jude!!' - to which i reply, iv never heard that song whos that.... they reply OMG and at that point they want to find out more about me.. its simple bt it works.
when i go out, i realise a good way to work on the game is to chat to everyone . dont just chat to hot people, chat to men, ugly girls and hot girls and adapt what works in interaction to your persona. - work yr way up to chatting to the HB's if yu need too
be interesting and completely natural and be kooky.
rely on context, theirs so many simple lines that can get yu into a set,
'wheres good to hang out in (insert city here)'
'will you take a photo of me and my friend?'
'i love your hair - its nearly as good as mine' (this is my favourite, simple but it works)
im new to the forum so sorry if my writing doesnt come across in a completely understandable way feel free to pm me if yu wish
best of luck !
