I have lack of air element or emptiness
Now the air is not completely missing from my chart because I have DSC in Libra and MC in Aquarius. However, no astronomical body comes in the air element.
Just my personal experience: I have struggled with oral communication throughout my life and I am still doing some extent. I am much better in written communication (although not very efficient) but when I speak, I have difficulty bringing my thoughts to AIR and adding my thoughts to sentences together which are considered strange or wrong. Now I came to know why I was always calm in school and work. But I think there is something else inside me that I should mention:
I am attracted by all things related to wind, clouds, lightning, angel, heaven, air element. In fact, an unhealthy passion towards them can be to such an extent that many things in my life seem heavy in small things and I am easily stressed or overwhelmed. I think I have something lacking and I try to compensate for it but in strange ways. I just want to go somewhere else.
