Pickle I don't know if you misunderstood my meaning, but I wasn't for a minute suggesting that the OP was lying. I was trying to tactfully suggest that the OP may possibly experiencing either an acute/transitory or chronic period of psychosis/fixed delusional beliefs. I didn't want to alienate/frighten/alarm the poster by saying this overtly, so I was trying to tactfully suggest that this may be the poster's reality but may not in actual fact be the case.
Although I'm sincerely not diagnosis a stranger on the internet, in my professional experience of treating people with delusions/paranoid beliefs/fixed beliefs this could be the case for this poster. This would be:
a) very possible, given the OP's posts and how much they chime with very regular themes and vocab used by people with paranoid delusions. Also could explain the self-contradictory and befuddling factors here such as not being at the cognitive level of problem-solving around personal care yet able to study Law at University. Not being able to leave the house to seek help but presumably attending lectures. These things are in themselves non-sensical (although I agree that my use of the term 'nonsense' was inappropriate, and I apologise).
b)neither derogatory nor stigmatising - there is no value judgement involved here (unless people attach more stigma to functional mental ill-health than to diagnoses of autism etc)
c)potentially helpful for the poster (as was my intention) and for other posters who may wish to consider this as a potential factor that is going-on for the OP (and which may guide the suggestions for help and support).
Just to reiterate - I am not saying the OP definitely experiences delusional beliefs - all I'm saying is that in both my professional experience (psychiatry) and my personal experience (I've experienced a period of terrifying paranoid delusions) for a person to experience such beliefs is common and far more widespread than perhaps many posters and the general population would realise. Therefore it might be worth MNers considering this when in discourse with other MNers who are giving accounts of what they believe they are experiencing.There should be less stigma around that type of illness, and we should not be afraid to raise this as a possible area of concern for the OP.
