I know the frustration! Though for me it's more that I've been struggling to get any mental health support because I present well and I have sought to understand my condition. I haven't seen a mental health professional since being diagnosed 6 months ago!
I know of people though who just don't care about their health, take as many substances as they can, they steal to fund their habit and because of this they get offered all the help available but turn it down until they get sectioned and hospitalised. Only then do they comply and that's just so they can get out again. Grrrrrr.
