Yes, when in pain. The slightest thing used to set me off but since moving & encountering people who fly off the handle at the slightest thing this doesn't happen very often.
From my stays in similar places, I've often thought we aren't allowed to show our full range of emotions. Someone who's not disabled is just having a bad day – if we ever get cross it's this huge problem & a RISK.
The OH has a temper on him – it's literally as if mine has evaporated & gone into him – & he hates being told what to do & sudden noise – when he was struggling with something, the staff member that was with him insisted he could manage it, which she does with a lot of us. "I ….can't ….." he slurred, slamming his fist on his chair. She wouldn't stop going on at him. He exploded, to a soundtrack of further comments about how he'd end up in a padded room. Oh, that's really helpful.
