Need some help/advice

My name is Katie and I'm 27. Ive had epilepsy since I was 3.The kind I have are Tonic-Clonic. Ive been told recenly that I should apply for disability. I've been having them more frequently.I take my pills everyday twice a day. I even have an alarm set on my phone so I dont forget. I dont even know where to begin. I've been at my job for almost 2 years and have had 4or 5 at work. The most recent one at work was about a week almost 2 weeks ago and I was told by the security guard at the front desk that I needed to go home and rest. Well when I talked to my manager the next day (talking funny from biting my tounge) and she told me that it pretty much goes against me because it was only a "suggestion" and I went home. I'm not allowed to drive anymore and havent been able to for the past yr. A girl I work with and lives by me and picks me up and drops me off. I get an occurance anytime when I miss work the next day to recover after having a siezure at home before work. Majority of the time i dont know who anyone or what things are. Sometimes I dont know my name or the date until a little later. I feel like a user because I have to get rides everywhere. The girl that picks me up for work she got a new shift. So i put in for a medical accomodation for a new shift so I can go to work and help customers. I work in a call center. Well after filling out the paper work and faxing them to my doctor to fill out and they faxed it to HR. Well they denied it and gave me a "temp" sched so I can get a ride to work. I cant afford a $40 taxi 4 times a week. No public transportion in my area. They told me to fill out a form for the handicap bus. I was actually kind of offened by it. I still have that temp sched. The city I live in my sister lives here to. Other family members live at least an hr away. My roommate cant give me rides to work cause of her work. As sad as it sounds I cant ask my sister. She wont do it and acts like the world is ending even tho I offered her gas money. I'm not with anyone. I feel like every road leads to a dead end. I have to work to live. I've even had to get about 7 stitches a few months ago cause when I had one at home thankgoodness my roomate was there I ended up face planting it on the kitchen counter. I dont know if I feel like I'm being discriminated at work or what not. It impairs my able to speak after haing one and being able to work that day or days after until my toung is healed. I have acutally had to go to work the same day not to get an occurance. Parts of my life are impaired because of having epilepsy. Its soooo upsetting and hard not to cry along with the embarrasment. I'll stop the novel here. I need some help/ advice. Please and thank you.  Oh one last thing I actually started to take online classes.
