That's sad
We're probably friendly because I've worked on myself a lot, for many years. I've had a lot of psychological problems, but now I feel quite good with myself. Well, except from my ADD.
Recognizing and accepting her existence helped, too, as she's been trying to draw my attention for quite some time. Persuading her I do want the best for both of us was a good ground to start talking. Who knows, perhaps your "thing" is also, deep down, a pained person thirsty for a hug.
To be honest, I wouldn't mind to be two people forever, as long as we can think and work in unison.
