Hi, is Winnie eating and pooping as normal? Does she look swollen anywhere? Any obvious pain? Is she drinking? If you offer her favourite bit of veg does she eat it?
Does she seem 'fluffed up', does her belly feel hard?
Does her breathing appear laboured?
These are some but not all indicators that something isn't right and that your pig needs medical attention. A hard belly is extremely serious, one that stops eating and/or pooping, again needs urgent help. again one who has lost it's energy (as yours perhaps has) needs help from a vet as it could be an indicator of something serious. Piggies tend to carry on as best as they can for a while, and when they lose their energy they can sometimes be at a point where they are struggling with what ever it is that's making them ill.
If in doubt the vet is always a good idea as piggies can deteriorate quickly.
How do you mean when you say her eyes don't look right, can you put your finger on what the change is with the eyes?
As a side-note she is not albino, albino animals are white all over and have red eyes, and piggies (even red-eyed whites) are not strictly albino, it's complicated. She is gorgeous though.

@Wiebke as she knows a thing or two about poorly piggies, as do some others here. If you can give us any more information that would really help. I do hope all is well xx
