It's So Frustrating

Today I realized how frustrated I am with myself, I just can not bring myself to care about others, feel sympathy, or relate to others. I am frustrated that I can not understand what others are feeling, I feel so selfish. I am frustrated because I can not help anyone because I don't understand these things, which leads to me not caring. I like helping people, but without understanding, I don't know what to do. I have met people who have been abused, who have been molested, or have mental illnesses; but I just can not feel any compassion or bring myself to care. I wish I could help.... so much.
