CW, I wish you lived near me! I have also been struggling with loneliness, which I agree is different from alone time that's wanted. I can feel lonely even in the presence of other people--though, in general, I find it's better to have as much non-alone time right now as possible.
And your D7 and mine would probably get along. We are in Boston this weekend visiting my cousin. We were in the car yesterday and my cousin was asking me about H's plans (not aware that Ds hear everything). H has a three month furnished sublet right now and my cousin said "And what's the plan after that?"
D7 chimed in: "He'll probably move back with us. Three months should be enough time for him to find himself."
I don't know where she heard the "find himself" concept, but it was very funny.
Anyway, as always--I am living something of a parallel life, if that's any comfort.
