In my case, it's a combination of disorganised and paranoid types of SZ, and BP. Hallucinations don't really bother me much unless it's dangerous/alarming smells or bugs. It's inconvenient not knowing what is and what isn't, but either it's rather obvious that it probably isn't or it doesn't matter much whether it is.

Delusions are different. Paranoid delusions were (and still are in some ways) extremely debilitating or, rather, incapacitating. But even when I think torture, poisoning or death are imminent, I still stay rather composed (I do tremble, but it's not exactly fear) and I don't become aggressive or anything and since thinking is so much quicker when fear is reduced by psychosis, I am pretty good at finding possible ways to escape, possible scenarios, even if I think it's unlikely to work. I'd probably always face death this way, which is comforting to realise: I know how I react facing the worst and it's rather good.

My entire belief system is delusional if delusional means: unable (or very hard) to be disproven (or changed) by rational means; interfering with normal functioning; and very important.

Delusions make you very creative and may prepare you for the worst. However, the chronic delusions can be extremely damaging, stifling. But antipsychotics do really very much help to make the beliefs less important.

I don't mind mania or depression (much). Problems with debt and losing income are big problems, though. But it's the chronic delusions that remain and lack of stimulation and reasons, causing self-sabotage, together with too much insight, that cause the most harm.
