what do you mean by "accepting"? To me accepting means being a night owl and not being bothered by it or its social repercussions. sorry, mixed with the note about the health event, it sounds like you sleep nights now, but that clashes in my mind with "living as myself" and "accepting". not trying to say it is contradicting, just that I did not fully understand it.
By accepting, I mean stop trying to force myself to be a morning person. This wasn't a trivial thing- the job I had paid well, and people depended on me. But I now do different work, that fits my natural rhythms.
