It's definitely not me. While sure, there are similarities (my relationships are all at least somewhat superficial as I don't trust people to accept me), but the majority of it doesn't fit me in the slightest.

From reading that, it sounds a lot like alexithymia has a lack of empathy, which to me doesn't correlate with AvPD... it's more related to NPD or AsPD. I also don't find that there's anything saying that AvPD aren't aware of their feelings (worded that wrong) or not recognizing others' emotions... nor is there anything to really make anyone think that AvPD people are cold/distant.

I'm sure that there are people who are both AvPD and alexithymic, but the description of Alexithymia could be applied to all of the personality disorders if you only looked at a bit of it.
