I know exactly what you mean, It can feel like a kind of domestic servitude, but self=chosen, so it's not. and as you say that distance from other people and what can seem like trivial , inconsequential things that bother/ occupy them. I felt that I was not my own person, and it was no good trying to explain it to outsiders, they just didn't understand, and could make irrelevant, sometimes hurtful or stupid comments. and them I'd feel even more isolated, so I tend to avoid such conversations. it was more of a stain to be polite when one is so tired, and they can seem so shallow. guess I lost patience.
all I can suggest is finding some supportive websites, where they do understand, people in similar situations.
yet I wish that time was still here, I mourn and regret everyday, seeing how much more truly present I could should have been. long to be now, and cannot. long to be loving, when I look back on lazy selfishness, and the unique preciousness of irreplaceable individual.
sorry. this no help to you.
good luck to you.
power to your elbows, and everything else that needs it.
