What can a person do about work, and epilepsy?

I have epilepsy, and I had a seizure over a month ago at work. The plant manager said If I keep having them I couldn't work there. The only way I was able to staay was because I had a doctor's permission slip. I work in a machine shop (so I can see their point of view) but, I highly doubt I will be able to find a job with similar pay (I lucked out with this one, 10 yrs. ago) and my bills are reliuant upon my current income. Am I shit out of luck?
P.S> I has a seiz, last night at work
I meant to put this in health section (diseases)
I think, that if you aren't allowed to make a living in your current field (your current job) the government should base disability on that income…..greedy bastords!
Some expenses I can't cut out. ie; child support. It's hard to make it right now, forget about a lower income.
