It's an interesting question and to those of you who have read my previous posts, the situation with my old school friend spending too much time with my sister when she has flare ups or bad episodes of lupus, basically I now believe she has aspergers perhaps, rather than scizophrenia - because I know schizophrenia is much more to do with delusions, hallucinations and hearing voices. I have tried to observe her when she doesn't realise it and she's not experiencing any of this - more she's trapped in her own artistic world - which is much more aspergers - but definately not autistic since she can communicate effectively with some people - other people she ignores like me which leads me to the big question - why does she do this?
I know my friend inside out and just recently she has had a bad week directly caused by her lupus, her medication for lupus has had to be double - by the gp and she has to wait weeks, months to see her lupus specialist again. A week ago, for one week she had swollen limbs and bad sweating at night. She was unfortunate to have locked the bathroom door when she suddenly felt very faint and had to scrape up every bit of energy to unlock the door so her mother could get to her. She was almost passing out and was severly sick several times. But bless her she still met me and another old school friend just a day or so after this happened so she has guts and even drove the car to meet us!
She's very artistic and can spot intrecate detail and patterns amongst living things. She's very artistic but dramatically lacking in common sense sometimes and has absoloutely no teaching ability at all. For example, I did teaching English in Spain for a few weeks, but I found it too stressful to continue. However, I can admit that I have an excellent teaching style and I was everyone's favourite teacher! Part of my success is not to be too clever in front of the students and let them tell me what's what. Then when I have their trust and confidence I teach them the more difficult side of English language and grammar points which does baffle some but at least they do ask questions where they feel stuck and feel they have learnt something at the end of the day.
My friend would make a hopeless teacher - well if she was trying to teach me something anyway because she really cannot communicate ideas really and does not give equal attention to people if she is talking to more than one person. Instead she concerntrates on one person and leaves other people out. When I was teaching an individual you can get away with this but two people you can't! Just taking too long to teach her any person skills - looks like she's going to be stuck in a warehouse doing IT in poor lighting and conditions for the rest of her life - unless I can have an influence on her somehow.
To Assume your friend is not paying attention or may not be a good teacher because of the possibility if Aspergers is not fair to her. Do some research on Lupus. You will find that difficulty concentrating is a major symptom. It is caused by neurological aspects of the disease, and can give others the impression of not paying attention, being disorganized or forgetful,confusion and fuzzy-headedness. I am a Lupus patient, 45 yrs old. Hold an advanced degree ( which was not easy to do with neuro issues), and have days when my brain feels like mush and I cannot carry on a conversation with more than one person at a time. I am a writer and because of my neuro problems have difficulty explaining something verbally, but have no problem doing it on the page. This may very well be what your friend is experiencing. This isn't about you, it is about her and her struggle with Lupus. Be a better friend,leave your ego out of the equation when dealing with her.
