It does sound like you've got a lot to work on. Going into counseling might be a good idea for you. All the degrees in the world aren't going to get you very far, if you can not learn to interact with people in a more satisfying way. You owe it to yourself, to not accept your difficulties as hard-wired in, though they may kind of be. Some of your problems in getting emotionally satisfying relationships are do to an outlook you have that you could change. That's a big thing to undertake, but I think you'll have a better life, if you do.
