What personality disorder can you have whil still being capable of empathy and emotional reciprocation?

It seems that my therapist believes I have a personality disorder and that it is definitely not Antisocial Personality Disorder. I have a conscience, a lot of empathy, the capacity for some strong emotional attachments and the ability to reciprocate emotions including the capacity to feel love for others, very strongly and in a non selfish way. I am also highly suspicious and contemptuous of anyone who lies or fakes emotions for peer approval, apart from to small degrees (ie. people with naturally bubbly personalities who are just outgoing). I used to feel strong hatred and still feel disgust for most people and strong affections for some people where I will do anything for them and feel a great amount of compassion for their pain and a desire to help them end it. I have mood swings and am generally a kind person who chooses out of empathy and kindness not to exploit and manipulate others for my own gain and have controlled small impulses to do it when someone is a good person, out of having a conscience and concerns about hurting them. I have manipulated others when they have tried to manipulate me with no remorse because their unkindness towards me made me angry. I do not seek admiration while I like to have it; and have a need to be around people and have a purpose in life in helping others who are in bad situations because I feel for people who are disadvantaged. I am only starting to like myself now and would like to live dependantly as soon as I can find work and would be capable of doing it. I am not too dependant on others; and resist the secretly very strong need of approval that I feel inside and do what is right even if it is sometimes hard to do. I come across as being a nicer and far weaker person than I really am and people seem to take my side in arguments even when I'm wrong while I don't encourage people to take either side. I worry about being without friends and family and have started to feel needy while I refuse to let it interfere with life and get in the way of others. I am overly affected by other people's disapproval of my thoughts and actions and get overly anxious worrying about how my actions or thoughts affect myself and other people and get overly upset if let down by other people and set very high standards for others and for myself and make an effort not to be critical and pessimistic but this takes effort. What disorder would you say this is?
