Sorry for the late response. I couldn't read and process much the last few days and before that I might've been slightly manic or mixed. Probably mixed: my memory is extremely bad lately. Ah, well.

Thanks for the answers.

Delusions are also misinterpretations (or they may cause them, rather) and of course not all misinterpretations are delusional, but the way there is a quick interpretation and quick response, having jumped to conclusions too quickly, which is, albeit mildly, maybe somewhat delusional, I think.

The bases for the delusions (which are also more or less delusional; I don't agree they have no basis, at all) may be being undeserving or seen as different or doing things differently and being unable to explain them but knowing they are right and believing all one's behaviours and one's very core of one's being are very much one. Any criticism is seen as complete rejection of oneself and it causes such confusion and helplessness that one fears abandonment.

All that is just slightly delusional. It's mild thanks to expressive and (almost) intentionally self-damaging behaviour, I believe.

I think theorising has helped me with many problems already. Self-damaging behaviour is still a problem, but the problems with fear of rejection and frustration and confusion are a lot less severe thanks to analyses and theories and all that. It allowed me to be a like Stoic, a Buddhist, mindful and rational, to not interpret and express emotions too quickly. To be more nuanced (mainly about people, which is what matters most).
