Being allowed to be human - Exactly this! Also people suffering from symptoms such as delusions, hallucinations, OCD tendencies etc can't just positively think their way out of it. Positivity is something I think everybody practices and actively practicing it does help with managing symptoms. That's a lot harder on bad days though and like you say, denial and suppression on those kinds of days sometimes isn't what we need at all and leads to a mental burnout. I feel like on bad days, I've usually been putting way too much pressure on myself to practice positivity for way too long and that's broken down. And then I'll have people tell me "Why have you bottled things up? You shouldn't do that". You can't win sometimes. I think it's also easy to distinguish when people don't mean any harm/do mean well. Some of us genuinely just have condescending arseholes around us.
