Novices and newbies discussion

I need your guidance. My recent foray into chastity has inevitably concluded, and it ended in failure. Despite my cleaning checks, I noticed blood and significant problems this morning around the ring and foreskin. This meant I couldn’t re-enter (the reason for checking was that a testicle had slipped out twice—once at night and again during a shower—I intended to switch to a smaller ring) so I’ve decided to pause while everything heals. It looked okay on Wednesday. So, being new to this whole thing, I have been quite foolish. I should have stopped and allowed healing back on day 14 when there was an issue with the foreskin connection that will take some time to resolve, if it ever does. Thus, advice: how do we handle the emotions tied to total failure caused by our own inability to properly inspect things and our tendency to make stupid decisions? Thank you.
