Soup, I'm very glad that you're gonna talk to your GP.
I really hope that it works out- it takes amazing bravery and courage to talk to someone about it.
I emailed my therapist recently- turns out she's not in today.
I feel like I've been asking her the same questions and telling her the same things over and over. :\
As far as mindfulness, I'm the type of person that'd say in response to that, "So everything is discrete? If I enter into emergency surgery and the doctors do everything they could to save me, but I die anyway. Does that mean they did not try?"
But that's just me.

I hope it works out.
