Thank God for your story. It comes as a fresh breeze of hope in a dark time. My story is very similar to yours except that it happened when I was out of college when I was 25. The last 3-4 years of my life have been awful (you know the story). I went through a really acute phase for a year and with the help of medication I was able to gain some ground over the most severe symptoms, enough to go back to graduate school. While on medication, my debilitating anxiety was at bay, but a constant numbing and emotional detachment still persisted, and some remnants of derealization (mostly manifesting as 'sensory detachment' and my visual field still not looking as it should).
I was wondering if you wouldn't mind clarifying a few points:
1) Did you experience sensory detachment (things just aren't as vibrant and you can't 'feel' them like you used to). Did this go away for you? How good do you feel now?
2) Did you have visual strangeness (fogginess/pane of glass) from the derealization - did that go away as well?
Thank you for your hope and for being an inspiration.
