my lovely Vicar didn't (thankfully) do anything like that, although she was acting highly irrationally, and was delusional, she was seen wandering up and down our quiet street. And when friends that know her approached her she was totally delusional. Anyone that didn't know her would probably have assumed she was high tbh.
She was admitted to hospital, didn't speak for nearly 3 weeks, and stayed in for several months. Thankfully she has now made a full recovery, but her mental state at that time was discovered to be through a lack of oxygen to the brain, caused by untreated curvature of the spine which meant she had limited oxygen getting to her brain. She's now on oxygen 16hrs a day and has (thankfully) made an almost complete recovery (although is only back at work part time).
My best friends DD has the same condition, although much worse (needing regular surgery to help her grow properly), and diagnosed in the womb - it can be genetic so possible that these girls weren't high on drugs, but had a medical condition.
I'm not saying that this is what happened with these girls, they may have willing taken drugs together and have been as high as kites through their own stupid behaviour.......but we don't know that. And for that reason I@m not going to make any judgments about them.
Yes of course I have the utmost sympathy for those that witnessed/dealt with it. But I feel sad that you think that anyone that is acting in a dangerous/delusional way should have no sympathy directed at them too.
