What a thoughtful message, ItsTheWooo. It had a great effect on me. The biggest challenge for any of us is the development of our own selves.

From what you posted here, your previous self had the same problems your self does now, you simply blamed it on the weight? One thing that did for you was insulate more than your body. It insulated your entire self from actually interacting with others, and carving out your own space, of whatever size.

My reaction to your points is not to assume you have Social Anxiety Disorder. You simply don't have any social skills! Without the usual routes to developing them through school and work, they are simply laying dormant.

What the next step will be depends on your particular style. Do you like to sit and think, self contemplate (which can be scary but very exhilarating, like a thrill ride.) Are you comfortable going over thoughts in your own head? And if not, why not? After all, you are the person who knows you best. Old ways of thinking will not work now, so you simply need to come up with new and better ones.

This feeling of being lost and unanchored will gradually go away as the real you emerges. In a way, you are like a kid again. You are creating a new person, without the armor that kept the world off in the distance. Start exploring it, and look on the tremendous strides you have made to self-realization; not only in your body, but in your mind.

We are all, always, on a voyage of self-discovery. Enjoy!
