Reengaging the Heart after a Heartbreak

I have begun this spiritual journey in order to learn how to process pain. My heart was broken quite severely as the result of a relationship that was terminated. The pain that followed was quite intense. This fear of loss translated across the plane of my life (fear of losing parents, fear of being without romance, fear of not being wanted, fear of being alone). I began searching within myself to find a way to be self-fulfilled and not need anything external to fill the depths of my heart; that is where I’ve found trouble in the past.

I have found now that I am able to enjoy the people whose paths I have crossed without attaching anything to them. When our paths split, I feel nothing terrible. I cannot decipher whether I’ve trained myself to turn off emotionally or I am living with higher understanding. Or is it both and I’m on the right path?
