Dont know if your Uk...but i get disability as i had to retire on ill health grounds...like you i have worked all my life...and it wasnt my choice. But i think for some of us we get to a point ...where symptoms are overwhelming and flares become normal.
Make changes sweetheart, the transition will be hard, but its is temporary feeling, and you can establish a gentle life...money can be tight...but the choice is worth it. X

Get lawyer that specializes in disability and only gets paid after you do. Make sure you go to all dr wants done like xrays, mris. Put on form that you have seizures too and depression anxiety whatever. Keep all paperwork from drs. If dr will write letter in your favor that helps. Good luck!!
