My mood's crashed after my not-a-date

As the title says, since my not-a-date (I decided that I was reading too much into it) a week ago my mood has crashed once again; it's not about sex (although my likely future, without even just physical closeness (unless I become good enough to visit a sex worker), does weigh down my mood); it's about going from a day-to-day life where I don't even have any outlet just to talk to people, to a meet-up where I felt like I was being listened to for the first time in years, back to that day-to-day life.
