Some people seem to use 'mental health' as an excuse for poor behaviour?

[Howlovely]

I've just seen on my local Facebook page a shouty post from what I assume is a local young woman having a go at the man who questioned whether she should be in a disabled parking space. She admitted that she is not a blue badge holder but "I have mental health" and it's none of this man's business. She had needed to go to the supermarket to get some food, which now she couldn't eat as she was so upset, so this man had caused her to starve and she hoped he was happy with himself. It really was a huge rant.
Personally, I think she's just an arsehole. Looking at some of her previous posts on the community page, she is an attention seeker and often details at length about her problems in order to get sympathy, favours and, sometimes, free stuff.
Mental health issues are, thank goodness, beginning to be taken more seriously, although there are still huge improvements to be made. AIBU to think, with (maybe slightly lessening, but still) stigma attached to MH issues, it is not helpful for people using (real or self-diagnosed) MH issues to behave like arseholes?

I agree neuf,
Very few on this thread understand what it’s really like. I am most upset at the ableism masquerading as stopping MH stigma.

This too .

Yanbu. It was the excuse for my miserable childhood. Maybe she did have a very mild problem, but strangely enough she was never overcome by the abusive parent symptoms when there were witnesses around, and they were vehemently denied in public.

And someone at work that only seems to have anxiety when it's convenient. Eg when they want their own way about doing/ not doing something. Or as an attention seeking/ victim tactic.

Especially frustrating because not only does she make it harder for those at work with actual mh difficulties, but she expects them, along with everyone else to bend over backwards to accommodate her bullshit 'needs'.

planderaccord not in that situation, of course you can't. Sorry, I didn't fully explain myself properly. I remove psychotic episodes/reactions out completely from what I was saying, that's totally different (it's tricky explaining). There's absolutely no way someone in that instance knows what they're doing so I don't count it as behaving badly, does that make sense? It's the same as someone has having a fit, they can't help reacting in a particular way so you would remove any judgement of behaviour out of situation. Does that make sense?

Its a tough one to word, I'm not sure I've explained it right this time
