Have you had a diagnosis, and a treatment plan for your illness, OP? I know there are some things, like fibro and CFS, that can be tricky to diagnose, but if your symptoms are similar and your GP not much cop, there are online communities where you can get support and advice.
Also, as PP have said, it sounds like you have enough cash in the family pot to hire a cleaner and perhaps some childcare as well.
If you have a longterm condition, you will need to get some sort of paid support structure in place. It's not fair or reasonable to expect your H and your family to run round after you all the time, indefinitely. While it's understandable that someone who is in chronic pain can feel angry and sad and frustrated, it's important not to let this turn into full-time needy, whiny, self-obsessed behaviour, as this leads to friends and family members becoming more and more resentful and reluctant to have anything to do with you.
And there certainly are some people whose 'illnesses' are self-diagnosed, and who use their alleged ill health to be the centre of attention at all times, because they are basically lazy whinyarses too 'frail' for this wicked world, etc.
