I have only 'told' relatively recently and never detail. Like you Britt was 30 years. Not sure when it was, think it was October, for sure, maybe again in February? I really can't remember second time. Just recall being at the end of the line. Anyways, because of this thread, was thinking maybe I only made it because I overestimated the gravity of it. So I looked it up. Apparently not, they say it's not only highly likely to be fatal (inevitable) but if stopped in process leaves tremendous damage, disfigurement etc. And most painful way to choose to go, according to prevention literature. And can even kill you up to one month after. (What a topic. :( ) But no wonder I felt unwell. Of course, couldn't tell anyone and my fault, so..
Yes it definitely makes for shame, etc.
However, I guess that means at some miniscule level I really was supposed to be here. Or people who cared were protected from me causing them more pain, for that I'm (very) thankful. (Though that causes more shame, too.)
