I've raised £400 to Raise money and awareness for Lyme Disease

I am doing a sponsored skydive on 22nd September to raise money and awareness for Lyme Disease as a friend of mine, Wendy, has been diagnosed with this disease.
I have known Wendy for a while now by doing classes run by her and her partner Simon. They have both taught me so much and i would like to do something in return for them.
Wendy and I used to train together in class doing Krav Maga, now Wendy struggles to do alot of day to day activities and has had to give up classes which she loves. Simon now runs most of them on his own as well as taking Wendy to hospital appointments and looking after their boys, which unfortunately one of their boys is now showing signs of Lymes.
Wendy is willing to sacrifice her treatments to now pay for her sons as they can't afford both.
Please help me to help them so Wendy and her son can get the treatments they need.
