Giving oxegen to insecurity or to mild comedy?

Do you ever phone someone up, to arrange a time to meet up, only to then get scared that if you don't stop talking to them now, you won't have any conversation left fo later. It seems to me that this is based on some sort of profound insecurity, based on some idea that you have not lived and ultimately there is no path of escape from this monster because nature abhors a vaccum so it allways fills it with something but at the same time this insecurity creates paranoia and thus if you were to start doing more things thus filling tha vaccum your self in a way you would only give the paranoia oxegen the ironic thing being that there is allways something to talk about, the best thing to do is to fill the vaccum with your self.
