"At what point do you decide you just cannot work anymore. I have suffered from chronic fatigue for decades but I just don't know how much longer I can work a full time job. How do you go about applying for disability?"

Hi W,
This is such a stressful time...making these decisions to step out of your career for health reasons. My company made the disability decision for me, I had no choice. I had runout of sick time and had used up all my short term disability so they basically terminated me but gave me company paid for disability. They also gave me a lawyer to pursue Social Security disability as well. I know you can apply for SSDI yourself. I would get on the Social Security website and investigate.

I would first inquire if your company has disability benefits and if not, apply for SSDI now as it can take awhile to be approved and some folks get denied initially and have to keep trying. I was denied initially but did get it so don't get discouraged. The lawyer who I worked with said he never had a client who did not get benefits after 2 denials.

I believe there is a forum on disability benefits here on Neurotalk that you may look at as well.

Sorry for what you are dealing with. There are of nice folks with good info and advice here.
Take care and welcome, Diandra
