I think people have varying degrees of empathy for a reason. Take for instance me, I have too much. If I worked in an ER, I would be a mess....sobbing and crying for peoples pain and I'd get nothing done. Take my oldest son who wants to be a nurse....he would do great at a job like this. A therapist who can't empathize wouldn't be useful to me or help me get better. We need all kinds of people in this world and as long as you don't intentionally harm others, don't beat yourself up for not feeling the pain of others....it can be a liability sometimes. In time I'm sure you will be in situations where you are able to empathize. Focus on what you do have as I'm sure you have an abundance of good qualities.
