Fundraising/Sponsoring Ideas

Hello,I am unsure how to go about this so i will give a little bit of info of my past and my current situation. I am a 23 year old female and I have had seizures a long time, they started when i was about 10. It took quite a long time and after many misdiagnosis's my drs finally figured out i had epilepsy. I have the type of seizures that causes me to go unconscious and apparently i shake and jerk violently, i have been told my seizures last from 30 secs to about 3 mins. It takes me a bit to come out of my confusion afterwards and I tend to fall down a lot. I do take meds for my seizures and they have cut the amount of my seizures down abit, but not enough for me to live a 'normal' life. I would like to be at least somewhat independent and my dr has even suggested that i get a service dog. I have been struggling with my insurance for months, and after like 5 months they told me that they did not cover service dogs in my insurance plan. They suggested i either do a fundraiser or get a sponsor. So that is what i am looking into. If anyone has an idea on a good fundraiser idea or perhaps someone knows of a possible Sponsor, i would be most appreciative! (p.s. sorry if this isnt the place to ask. i am very unsure of who to ask about this and my insurance is very little help with info.)
