Thanks, is nice of you to suggest. It's just been already over 2 months now, and I'm still basically spending most of my days incapacitated by grief and self-hatred. Also I feel I don't want to be with someone else than her, no one else interests me and sleeping with other people for example just makes me feel more depressed and empty inside. She doesn't answer my calls or texts anymore and seems pretty set on forgetting and disowning me, so there's little possibility of sorting things out with her. Maybe that's not a bad idea, and perhaps I would do the same if I could, but she just causes me such impossible amount of pain and regret, I'm not entirely certain why :/ ... I tried to talk about it with a few therapists, but they were largely unable to offer any remedy. I have good things in life too, and I don't think the world is all bad, but the pain is so overwhelming, and it doesn't seem to be lessening at all even after a significant amount of time. I can't deal with it anymore, and I just think my whole life was a huge mistake that I want to at least marginally rectify by putting an end to it.
btw this method didn't work for me, but maybe I just didn't try hard enough, i donno.. I was hyperventilating for at least 5 minutes or so very strongly and did everything according to the instructions so far as I understood them right
