as somebody who also has seizures I feel your isolation. You have had a series of dramatic 'life events' and I think it is natural to get po'd. Now - let's concentrate on the pluses:
you now have medication and hopefully it (or another dose/brand) will controll the szs.
You have a place to live; perhaps not what you would like, but better than alternatives
you have us (we are an excellent problem solving and venting board

)
My advice: contact DMV and verify how long you need to be declared "controlled" so that you can drive again {each state has different rules and they can change every so often}. It wouldn't hurt to get in touch with your local epilepsy foundation chapter either as they can give the ins & outs of driving restoration.
if all else fails - rememebr we love you!
