What I write here is borne out of long and bitter experience.
Once upon a time, I believed in a great many things I now find unfathomable. I believed that people were basically okay, if slightly selfish on average, but fundamentally similar to myself in that they simply wanted to coexist and learn about themselves in the process. I did not specifically believe in "love," per se, though I did not specifically doubt it either. I was nonetheless surprised when I encountered it in person. And, later, disappointed to find it so much a house of cards, like so many other things.
Few can understand my lack of interest in romantic relations by this point. I feel like I've already been there. I've fallen head-over-heels in love, I've enjoyed a long-term relationship, I have memories of precious moments... there's a check in the box, you know? And given the price I paid for it, in the end, I am not eager to repeat the experience. It was worth having once, but only once, if you ask me.
I digress slightly. Upon my separation from my former partner, my social circle immediately collapsed. My separation was caused by the unexpected death of a childhood friend, which left me rather depressed. In turn, the separation caused my social network to disintegrate.
This bears repeating: my need for emotional support immediately destroyed my social network, starting with those closest to me. More generally, most "friends" (and those even closer) are only there until you actually need them, then they're gone.
This is not a unique pattern from what I have observed, but instead is rather endemic to human nature. People like to have fun, basically.
Drawing upon my experience (which I have glossed over very quickly here), the most apparent suggestion is that the concept of a "support network" -- a collection of people whose acceptance your self-image or emotional well-being hinges upon -- is fundamentally flawed. More bluntly, it's a recipe for disaster.
The question, then, for ADISC is: how do you minimize your need for the acceptance of others? How do you learn to be content with yourself independently of anyone else's approval?
