My 7week old kitten has an eye that is swollen red and has discharge we are going to take him to the vet he also keeps sneezing I feel so bad for him it's so sad I can't even wait two days to take him to the vet I'm worried about him

He could either have a cold or allergies.
Are you letting him outside?
Is he in a room that is carpeted or has something he could be allergic to?

Until you get him to the vet try putting him in an uncarpeted room that doesn't have much in it to see if it starts to clear up. And don't let him outside.
