How to make efficient PhD research in absence of the supervisor?

I am a PhD student, in my situation I work totally alone and freely , the good thing here is that I have learned to be autonomic and I can guide my research by my own, however, In comparison with the other Phd student , I don’t have a guide or even a corrector that I can discuss my work with; so that; as a solution I feel more comfortable when I write, still less experienced, but when I write I read and I learn more and more, for the moment, writing replaces the absence of my supervisor!!! Working alone is not so dramatic; I try to extract the maximum of positivity facing the challenge of doing a PhD almost alone, I shared my experience because I’m curious; what can we learn from that? are there student in the same situation? If not; what would you do in such a case?
