It's easier to be sympathetic to a diabetic who breaks out of their 9-5 job and goes rogue due to mismanaged meds/dietary regime resulting in low blood sugar than it is to be nice to someone who's been tormented by mental health issues and took some "time out" from their meds. But this distinction is wrong. People with mental health issues can be more defensive because they have had to live with, and integrate into their sense of self, the socially problematic parts - this does not make them somehow "worse" than the diabetic raving their head off. It just means they have more on their plate to cope with, and that's all. JMO
