Thank you, erodedthoughts, for all your help! I did refund everyone their donations. I do not want donations given under false pretenses, and do not want anyone to think I may have tried to take advantage of the situation. I wanted to give everyone a refund to show I'm making a good faith effort to correct the situation. I do still need the procedure for my eyes, so if anyone is still interested in donating, I would definitely appreciate the help.
