If I remember correctly:
I hold it true, whate'er befall;
I feel it, when I sorrow most;
'Tis better to have loved and lost
Than never to have loved at all
(In Memoriam AHH, Lord Alfred Tennyson)

I don't know - I've never really experienced that someone I was attached to left and left me hurting. Maybe I just don't get attached like that - maybe I don't easily get hurt by it - maybe I've just been lucky so far. Who knows.

I'm not attached to my T. I'm attached to the care she provides, but if she quits her job, I'd be alright as long as there is someone else I can do similar therapy with.
