Worst thing to do is to beat yourself up and call yourself names. I have severe approach anxiety. It's like jumping out of a plane. You're out sarging for you and no one else. If you didn't open sets "it is ok!" because the good thing is women aren't going anywhere.
Just know in your heart it's ok to be scared. Then approach while being afraid.
Open up some guys, shoot the shit, get in a friendly mood. Have the goal be the approach not a #close or kiss-close. You'll feel like a million bucks because the goal was the approach not any results.
If you can't do it don't worry about it. I know if I had to leap from a plane right now i'd be scared shitless. Would I jump? Maybe. If there was a HB 10 waiting for me with her arms spread wide-open
Anyway, we can be our own worst enemy. Take it easy on yourself. You're not a "bitch" or any other name. You're human. Everyone...everyone!...gets approach anxiety. Just take the leap next time...or dont...it's alright either way.
