Wallah,
I recently took part in a "dryathalon" which is basically not drinking alcohol in January and raised some donations via Just Giving. However, I have also collected cash donations from work colleagues and friends and I am sure "Cancer Research" (the organiser of "dryathalon") won't mind me donating the surplus cash to the Rainbow Centre.
So sorry to hear of your condition and my thoughts and prayers are with you, your family and friends.
God Bless
