Sorry to hear that! I remember it well, it feels like death. I don't completely know why mine stopped but it's been years now and it hasn't really got me for ages. I'm still sensitive but I don't get that "I'm dying" feeling any more. I also used to have to sleep to reset.

I got out of a long relationship (13 years and 3 children!) which had run its course and that also helped - we're much better as friends and co-parents. I'm a lot more stable overall these days.

Wishing you a way through!
