OP... Give me her email address, I'm very good at these sorts of things
. I totally understand your position and want to shake her for you. Well done to your son!!
@failing I also understand your sentiments too, but perhaps it could have been worded better or perhaps have a bit of understanding for different circumstances? I have always been desperate to work (see below), but I also fully understand that everyone is different and we all have different ways of coping with what life throws at us. Doesn't mean that because I continued working I thought that was the 'mindset' (as it was described) that all sick or disabled people should have, or someone else is wrong because they are unable to work regardless of how you or others perceive the person with disabilities.
@fontofallknowlwdge access to work isn't always as you describe... Their physical help side left me feeling totally suicidal, worthless and as though I had asked for the earth. I have to say here that the mental health side was amazing but their help could not be put into place until the physical help side did their bit. Eventually mental health had to cease offering help and advised me (and directed me as to how) to put in a formal complaint.
Background, so you understand my sudden downturn after their lack of understanding, empathy or help.
I have battled, with a significant disability for 20+ years, along with severe depression but I was determined to stay in work, for a few complex reasons. I retrained because no employer would take me on. I became a well respected, knowledgeable and experienced SELF EMPLOYED professional and all my many doctors were amazed.
I was happy to be working, loved my job, the responsibility and the respect, but stressed beyond belief.
I thought I was not coping with work because of my disability. I sincerely wish it had been just that.
I started having bizarre vision problems and very odd neurological issues that I put down to exacerbating my disability due to working, stress and depression of working with my disability. I lost my driving licence... I needed that to do the work I did.
And here comes the bit about FUCKING ACCESS TO WORK
I asked for help with driving to and from work, that was all. I asked if and/or how they could help me practically. They never answered my question, the one question they could help with. The mental health side suggested that because I was driving to and from different venues every day, between 20 and 200 miles a day, they didn't know what to do. They had me fill in so many forms, send in years worth of accounts, explain why my profit margin wasn't higher... the crap went on and on. In the end all communication from them stopped, I was never refused it, they just never had the fucking decency to say they didn't know how to arrange the assistance and process my (unusual) request.
Over the following 3 months I was diagnosed with a devastating eye condition, am now registered partially sighted, awaiting the quickly nearing day of graduating to becoming blind.
6 weeks after that I was diagnosed with a (severely) life limiting neurological condition.
The sad thing for me is that, I know without a doubt, that if I had been given that support from access to work I could still be managing part time work. However, I am at home, alone, useless, worthless and every single night when I go to bed I say to my dog something like "wouldn't it be lovely if we could die together tonight" but fuck, I'm still here 
@OP I am so sorry if I hijacked your thread.... I had no idea how bad I was really feeling until reading your situation and the shitty crap from your family member. I genuinely hope things improve for you soon, until then, enjoy your crafts, and every time you move those needles, imagine them poking into her eyes
