I started going out with a fantastic girl a couple of weeks ago. Everything is great, except that whenever I've sent her a text message or email requesting something and haven't received a response yet, I experience significant dysphoric anxiety, fearing that her response will be not just "no" but "no and I don't want to date you any more". This is due to brain chemistry or personal history, take your pick—either seems like a possible explanation to me. But there's certainly no evidence supporting the idea that this is likely to happen, nor is the anxiety helping me prevent it or helping me in any other way.
Does anyone have evidence-based advice, or pointers to same, on dealing with this kind of issue? It is the only splotch on what have otherwise been the best two weeks of my life.
From personal experience the best advice is to date a lot and get hurt a lot and build up a thick enough skin to where you don't care anymore about the rejections.
Worrying about the rejection will only make rejection more likely.
Act as if you are a confident person, then other people think you are confident, and you'll become more confident. While of course actually trying to do things to actually become more capable too, since that improves your confidence as well.
The other ideas here also are good techniques too, but what I found is that when I had been burned enough to stop caring about rejection was when I suddenly became successful at dating. The main thing that had changed was not worrying about it.
How has this aquired negative points? This is the single best piece of advice in the whole woebegone thread.
