Yes, it may have been theoretically possible for someone else to notice and fix these problems, but I was deliberately taking actions that ended up preventing them from having a chance to do so.

Nitpick for clarity's sake: I've seen no evidence that this was deliberate in the sense implied, and I would expect to have seen such evidence if it did exist. It may have been deliberate or quasi-deliberate for some other reason, such as social anxiety (which I have seen evidence of).
