Hi Mulan,
Thank you for this post. I always enjoy reading your posts. You are intelligent and self-aware. I do not believe you are a half of a person. You are a full person. Certainly, you are different than the majority of your peers, but that does not mean you are worthless. On the contrary, you have the right to exist on equal basis with others.
It is not your fault that psychology has not helped you. I bet you have a condition that can be explained, you can get clues about your behavior and personality including tips to adjust your environment or yourself in a way you enjoy living more than now. The issue is that you do not know what is going on with you really , you do not get appropiate assistance and then you are going in circles.
Perhaps your family is having problems to recognize you are having a condition and, consequently perhaps they will not be of help. Perhaps you will have to do this by yourself. Something will have to be done, somebody will have to do something otherwise you will become more and more isolated. This somebody will have to be you. Sooner or later you will have to search and research about the best assistance for you, ways to structure your daily life so it is less stressful, ways to help you to connect better with others. Your life could be better, it is just you may need better professional orientation.
I send you a big hug
