Quick questions about disability and how much do you receive?

Since 23 I've been having a nightmare rollercoaster with my health. Endo has found I have addison's disease, diabetes insipidus, hypothyroid,hypogonadism, and we still don't know the cause or if it will get worse. I also have cramps and sore muscles days after I use them. Very little and slow muscle recovery keep me off my feet and unable to even walk on the treadmill for now.

Well I was in need to move out soon and get on my own, also getting plans to get married soon(yeah, wonderful timing..).

I simply do not have a steady schedule due to my health issues, and I was looking into Disability.. how could I survive on disability?

I doubt it will be much, but I just want to know my options.. and if I take it, pray like hell it will be temporary..
