I have a theory that AVPD is caused by the sufferer constantly escaping from the present moment, for whatever individual reason. They are in thrall to their memories of past encounters, especially the negative ones, as well as to projections and worries about the future. However, if we could learn to always be in the present moment, I think we would have a better time. Think about it. In the very limited moment of now, there may be a number of different problems or challenges, but only one action you can take to remedy one or all of them. When you are truly living in the moment, you can see clearly which actions are needed, and you take those actions. But when you are living in your mind, you are piling other things on top of that "now" moment - multiple interpretations of the problems based on feverishly going over similar past events, as well as future projections based on past experience. From these memories and projections, fears and anxieties arise. The thoughts and the crippling emotions are not one and the same, one causes the other.
If I was always TRULY present, I would never be unjustifiably afraid of other people, because I would not be piling on top all these thoughts about how people are untrustworthy, quick to mock, how I am a loser, I'll never succeed, and thereby creating the intense fear-based emotions which truly cripple interaction.
It may seem pie-in-the-sky to think about "when I'll be present", and in fact it is, because I'll never be present in the future - the future never comes. There is always only the now. All else is memories and fantasies.
Another thing that disables our contact with the present is our tendency to escape into fantasy and daydreaming. This is a bad habit that has to be fought off. But it's oh so tempting.
I like to think of being "in the now" as riding a bike (cheesy, I know). It comes easily to almost no one, until it is learned. Right now, we have all learned that the present is to be avoided. That we can never learn to ride the bike. When you don't know how to ride a bike, it can seem very challenging, and may not come immediately. Everything you have learned up until that point tells you that when your feet leave the ground, the bike will fall over. There will be falls along the way; there will be pain. You may even give up. But if you keep at it, you will generally learn to ride the bike after a while, especially if you have help. I think being in the present is like that. If you make a commitment to try to do it, and when you notice you've fallen away, gently and constantly remind yourself to get back into it, over time being in the present will become your habitual response, just as your habitual response to getting on the bike becomes not to fall over, but to push the bike forward as your feet leave the ground and keep your balance.
I didn't get these ideas myself, they came mostly from reading a really good book which I would reccomend to absolutely anyone. It's called "The Power of Now" by Eckhart Tolle. It is a bestseller and should be easy to find in the self-help/new age sections of bookstores. This book is my personal bible. It was the first book that ever articulated to me so clearly the roots of every social problem in my life. It's also not filled with new-agey, Dr. Phil-type jargon. It's written in plain, simple and practical language that anyone can understand.
I want to add that I wasn't paid to tell you this, I just think it's an incredibly helpful book for people with AVPD, if they were willing to put in the effort to apply the concepts.
I look at avoiding the now as a compulsive addiction, no less severe (although less physically debilitating) than an addiction to hard drugs. It stunts your life. And so far I have lacked the motivation to keep getting back on the "bike" of the present for long enough to actually retrain myself to live in the now, joyfully and easily. It's a learning process, just as people who are addicted to drugs and alcohol need to learn how to live in the world of the sober as part of their rehabilitation. But I have hope, and for now that's good enough.
