My new life for almost 10 years.

Hey everyone. My name is Ally. I will give you a little bit of my story, because I need some opinions. I am 22, on April 20th I will have had epilepsy for 9 years, being diagnosed when I was only 13. I have only had about 9 seizures my whole life, leveling out to about one a year but only due to my medication. One day when I was younger I accidentally missed one dose and ended up having a seizure that night. So my medicine pretty much controls me. Whenever I gain a little bit of weight I have one as well, so I have to work at maintaining my weight. I am actually on 4500mg of Keppra ER a day. My new doctor told me I was on too high of a dose so next seizure I have she wants to add some new medication on top of Keppra. I am sure a lot of you know that epilepsy medication is definitely not cheap. I have been trying everything I can to not have one. Every morning I wake up with a pounding headache and at least once a week I have staring spells which my doctor confirmed was indeed a seizure but mainly I have grand mal seizures, full blown shaking and loss of consciousness, falling to the ground. One day I was actually laying on my side when I had one, loosening the capsule around my shoulder causing me to get shoulder rehabilitation surgery in 2014. To this day though my shoulder "pops" as I call it and dislocates but slides back into place. It still causes quite a bit of pain, only lasting about 30 minutes but it happens like 4 or 5 times a week. I may actually have to get another surgery later this year, not sure yet. It was so bad that at one point when I just raised my hand it dislocated and one of my doctors said she had never seen anything this bad. I also have had scoliosis since I was about 10, getting surgery in 2011 at 14 and again in 2015 at only 18 and possibly another one as well. My back is always in constant pain, at least once every few months it has a spasm that keeps me in bed for at least 3 or so days. I have been told with all this I should go on disability and I have been considering it. I was always one to like to work for my money, even got my CNA (which has been my dream since I was a kid,) and have been trying out some assisted living facilities around me but that's not even working. I just want to live a happy life in as little pain as possible. I am actually very nervous to apply for disability with the fear of getting rejected. I was just wondering what other peoples thoughts were? I do not know much about disability and reading online I found different qualifications for epilepsy and disability. Thank you so much for reading this, ~Ally
