Is that possible to have avoidance type for strangers and anxious type when pass some closeness threshold?

Hi,

For the context, I have know I have anxious type for sometimes, but recently I observe and found I have a strange pattern, that I tend to be avoidance for people that I have little know of, and when get alone and come pass some threshold of closeness, for example some trust/connections been build through time, conversation, network etc. All of sudden, I can switch from avoidance to anxious, like sensitive to message timing and monitoring and over-explain instead of under-explain.

Is this a right understanding of my pattern?

Thanks
