Rowan absoluetly, though I doubt anyone seeing us out realises that ds1's nasty clothes are down to an issue and not something else. Youd'd be amazed how many people think they are kind and don;t judge until they do (thinking about the devout Christioan at school who preaches kindness all day until autistic ds3 accidentally kncoked her and then was all in with the 'control your child' crap- he only stumbled).
The HS I worked for was in a deprived area and had to close; I know of toehrs in similar areas that faced the same. Part of teh reason why handing some of these issues to Big Society scares me: if we coudln;t get the volunteers then...?
Binbag lady would probably be fairly easy to help; you'd want her to see a MH specilaist for counselling / scareening and then put in family support (a HS vollie would be perfect) to explain, coach, and then usually people like this have managed to make themselves quite isolated so getting them out and making friends 9we used to run family groups for this) is a big key. How do you know society's expectations if you were raised the same way (maybe worse) and never leave your sofa?
Of course, people talked about pride and it is a key: but I know as many people struggling who refuse help through pride. Usually people who are educated / maybe carers or made redundant, struggling to manage the system yet getting nowhere. Also not being abole to ask for help is common, indeed expected, in certain disorders that would predispose someone towards getting in a mess. Depressions, AS etc. Pride is a double edged sword.
it's not going to get better though. I looked into SW training; they now ask for 6 months unpaid experience locally, full time.. You won't get experienced adults with that, there was no way I could cover it for certain. I've found a route I much prefer anyway (am doing a day a week unpiad at a local SEN class, want to train for that) but a lot of people are being prevented who could offer a lot.
