@lightly toasted: Thanks for your forthright replies, using strong words i was too shy to use. I think this woman, having just met me, when i'm "up" and cheerful and joyful at the moment just assumed i'm a lot stronger than i really am. She hasn't seen me in the Winter when all i can say is "meh."

But we should never assume that people aren't suffering and that it's okay to dump.

It sounds like you have some loved-ones so you have some options re confidences but i don't have any family and i don't get along with professionals so peer-support is really my only option. Out of six calls this has been the only problematic one, so that's a decent record. I think if it happens again i will just say, "That's way too heavy." I did this once when a guy i just met asked me if i believed in God and it worked out well.

Still, i feel a weight on my chest.
