GECKO QUESTION??????????????????????…

I have a banded gecko and i used to have two but one of them got a parasite from crickets (my friend took care of her for a while and figured out about the parasite)

It started out with her not opening her eyes very often which made her run into walls. Then she had trouble shedding and i tried to help by rubbing off the skin with a wet warm paper towel, which got some of the skin off but not all of it. Then she got really thin and there was nothing i could do anymore. Now I have one gecko and he's started to close his eyes more and he's having shedding problems.

What should I do to help him? I cant take him to a vet. Could he have the same problem as my other gecko? and I've been wondering if I should give him away but that would be very hard for me because I've had him almost 2 years.
