Never thought people would change

I have a car lease and because of my seizures I haven't been able to drive it for over a year which just makes it an expensive lawn ordainment right now. The dealership has been less than understanding I went to the better BBB and the attorney general both saying they couldn't do much but sent a letter to the dealership saying they should do the right thing which they didn't. All in all I don't really care and it was nothing personal I wasn't making any progress talking to them directly. Anyway my dad and I drove up to the dealership for an oil change it was on the weekend and I didn't work. To say they were jerks was an understatement. They made us wait for what is usually a 40 min oil change to one that lasted three hours and they weren't overbooked or anything. Our sales rep that we have leased and bought cars through would always come up to say hi avoided us like the plague even shooting my dad and ten year old nephew that tagged along for the ride dirty looks. I didn't feel like what I did was anything that someone wouldn't have done in my situation. On top of that ever since I told my boss I have epilepsy she's been going out of her way to make me quit and making mean remarks about my situation saying they have been making accommodations for me. I am on work on time, my dad drives me not anyone from work, etc. I've worked there for 8 years and have won countless Employee of the year and top contributor almost every year and now I feel like I'm being treated like dirt. Like the seizures, side effects of medication, I have nocturnal ones that increase my chances of SUPED I think that what its called so I worry about not even waking up the next morning, the hours of appointment, and the times where I could barley get out of bed and still coming to work. Needless to say I fell apart after coming home from the dealership. I had never felt like my epilepsy interfered with my life and that I would be treated differently because of it. Driving was the only thing that I felt was difficult I didn't expect it. Anyone else encountered stuff like this before and how do you deal with it?
