I personally feel, eye contact can be a trust thing, an opening oneself up to being vulnerable thing, and at times, it can be about sincerity.

I tend to, life in general, have found myself, overcoming my desire to divert eye contact with others, not just therapists. As though, to not want to feel connected to them.

It took me, years to be able to trust sincerity of eye contact. I make eye contact with both my talk therapist and pdoc, now. I even make eye contact with my neurologist. Many people, it's a brief look, with them, can hold a conversation that includes eye contact. Takes time to reach such a level. I've been on and off again with the talk therapist, I have now, for about 4 years. And have been consistently a patient with my pdoc for over 4.5 years, and with the same neurologist for 6 years.
