Please help me get my wheelchair get fixed.

Hi my name is Amy, I’m 27 (almost 28) and I’m a wheelchair user, my wheelchair has recently been having problems, the back wheels shake aggressively when I drive which makes it hard to control and causes a lot of pain due to my conditions CRPS (Complex Regional Pain Syndrome) and hEDS ( Hypermobile Ehlers Danlos Syndrome) It is also struggling to get up ramps, doorways, drop kerbs etc because it pulls to one side and then stops. This means getting on a bus has now become dangerous if I’m alone because multiple times it’s pulled to the side and almost fallen off the ramps, I am unable to work due to my conditions and getting my wheelchair looked at or fixed is extremely expensive and it’s hard for me to afford with the cost of living crisis and my other bills. It costs £150 just for a service but that doesn’t include the parts that need to be fixed. If it can’t be fixed I’ll need a new wheelchair as I’ve had this one for 5 years now and 2nd hand they are £4000 and that is just wildly out of budget for us. We have asked around and repair costs are going to cost more than we thought and that’s even if I can get the parts I need. I hate that I’ve had to set up this because I don’t like asking people for money but this chair is my freedom and my independence and I can’t cope with it like this. I am so thankful for anyone who can donate or just share this go fund me so I can get my freedom and independence back.
