Hey Mr. Radio. That you seem to be so unsatisfied with this transition makes me think you're still an extrovert. You seem to be craving more interaction with your external and social world, but unable to get the amount of it you desire for some reason. The impression I get is that you have mental blocks making communication difficult for you, and because you are an extrovert, this is making you unhappy. I'm not qualified to tell you what that mental block is, but have you looked into it possibly being social anxiety, depression or meds messing with your clarity of thought?

I think if you were really becoming introverted, you would be withdrawing because you find satisfaction in it - speaking as an introvert myself, I crave that! Hopefully your therapist can help you work it out. I would hate to be forced to act like an extrovert for too long when that's not really me, so I can kind of relate in a roundabout way.
