When you first start sarging it's normal to be out of step, especially if you didn't go out that much before. First, get a cool hair and clothes. If you don't have any female friends, then you will have to ask women online for assistance, hire someone, or bug strangers for their opinion on the spot. That should give you an instant confidence boost.
Second, if you're depressed or suffering from some kind of emotional/menal problems you need to get that corrected. NLP/Self Help isn't going to fix your long term psychological issues. No one here but you knows if this is an issue. You are out there facng rejection, so you've already got 90% of guys beat. You should feel confident about that alone! You've got balls! One of the few, the prideless, the sargers
Do those two things and you'll start to get more confidence yielding more positive responses. Positive feedback yields improved self concept. See how this whole thing builds off something else. It's like math. There is a sequence. If an earlier problem hasn't been corrected, you cannot get into state. If you cannot get into state, you will get shyt responses.
It is also more important to learn the art of bullshytting than to memorize a million things to say. Going out often willl correct your social skills and you will learn what to say and when. Sounds like you're already on your way. The success or lack of is internal to you, not external. You are fighting a battle against your self much more than with the other males.
