I can relate to what you wrote. I had cold parents who I did not bond with emotionally. And, I've always been an introvert and an intellectual. I realized at a young age that my emotions towards others were not there. In retrospect, I was full of fear and insecurity because I believed that I did not fit in and was not accepted; fear and insecurity were the only emotions that I knew and they repressed my other emotions. I started to make a conscious effort to have empathy for others. I find that my emotions are rarely spontaneous. I have to dig sometimes and they will eventually surface. I cannot control when that happens. I have come to accept that my delayed emotional reactions are part of what makes me. Emotions are really the end result of a process; focus on empathy for others and bonding with others and the emotions will follow.
