In need of a new wheelchair

My name is Savannah Grayson, I have Cerebral Palsy and I am in desperate need of a power wheelchair, normally I would use my walker on a daily but ever since I started college, because the campus is so big it’s too much walking for me to endure. I’ve been using the wheelchair I currently have (not a power chair) everyday on campus, but I’ve already had it for 4 and a half years; it has broken down on me twice and it no longer meets my needs. Both of my parents are overwhelmed with college expenses due to my sister and I being in college at the same time, my parents do not have the means to purchase the chair that I need and the insurance will not cover it. A power wheelchair is the best option for me, being that a power assist wheelchair still needs to be manually operated and  it becomes very frustrating and exhausting for me, especially in weather conditions such as rain, snow and sleet. I would appreciate any assistance towards my goal, it would be ideal to start my new semester/sophomore year with this chair.
