In need of a new power wheelchair

Hi everyone, my name is Savannah Grayson. I am 21 years old and I was born with Cerebral Palsy, therefore my means of getting around are very important; It is a huge part of making sure that I am able to actively live my day to day life. I am currently in college and I use my power wheelchair, almost everyday to get around campus and other places that I need to travel to. Due to the fact of me using my chair almost everyday it began to break down on me and is currently on its last leg.  My power and speed buttons on my joystick have been consistently malfunctioning causing  me to not be able to use my chair on some days. Which has essentially been hindering my independence. One of the buttons also came off of the chair, so I am no longer able to operate that button. This isn’t at all helpful when I have school and other important things to worry about.  Now that I have had my chair for 2 years and some change, the joystick no longer possesses the same stability that it once had. Even when I tighten it, it loosens almost immediately which it never used to do. The joystick has even fallen out of its designated hole, while I was in the middle of driving it which is dangerous.  I am unable to put in for a new chair without having to pay for it, because my warranty for this chair was only valid for 2 years. So I need a new one ASAP. I am looking at a newer model chair that has a longer warranty. If you can find it in your hearts to donate it would be greatly appreciated!! If you are unable to donate, please please share!! Thank you all so much❤️
