Virtually every email and text message I write (particularly when I'm initiating) comes with some dose of anxiety, except with immediate family. I don't know if it rises to the level of RSD, but in certain situations with close friends, I've had panic attack level of anxiety. My coping mechanism is to tell myself "the best I can do is good enough and if not, that's on them" and force myself to just lob messages, like little grenades.<p>However because I have a lot of 2nd and 3rd level relationships to keep in contact with (for business) the stress can accumulate. My technical solution was to create my own CRM (<a href="https://humancrm.io" rel="nofollow">https://humancrm.io</a>) that is entirely oriented around follow ups with important people. It helps me quickly process follow ups and remove the analysis paralysis.<p>I also am told all the time "Thanks for following up, I am so bad at it" - so I've just accepted that a lot of people feel the same way and I'm going to have to make the first move.
