I'm resisting the urge just post a one line comment saying #humblebrags by posting the comment anyway and giving some advice :)
Below Joshua mentioned studying PUA and I agree. One method that works for me that I learned from PUA is to try to convince yourself that you don't care if she breaks up with you. Tell yourself "she's just a girl" or "there's plenty of fish in the sea" or whatever motivates you. I also combine this with a "just fuck it" attitude. If I find myself worrying about something like this, I'll say either in my head or out loud "fuck it. If she doesn't want to respond I don't care. I'm going to go play video games/exercise/whatever." (The "just fuck it" attitude only seems to work specifically with social interactions, in my experience. If I have reservations about other things, typically it's for a good reason)
Typical mind fallacy applies here - what works for me might not work for you or might have negative side effects, but you don't really know until you try.
So I think a variant of this approach is useful and a variant of this approach is really harmful. If you say "fuck it, she's not important," you'll be conditioning yourself not to care about her or even actively resent her for "making" you anxious. That way lies a lot of badness.
Nevertheless, I do think it's handy to come to terms with the idea that if she decides to break up with you, then it's not the worst thing in the world. It's an admittedly sucky but manageable state of affairs. You will be a finite amount sadder than you were wh...
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.
