Help me with my cat 😭

I don’t have access to a vet and can’t find any answers online so this is my last hope..my kitten has been throwing up food and water all day and idk what is wrong with him.. he is still active and playful running around the house and jumping out but he is constantly wheezing and gagging and this has been going on all day and I’m scared and don’t know what to do..I don’t have access to a vet right now and he hasn’t ate anything weird that I am aware of..does anyone know what this could be or what is wrong with him and how do I help him before taking him to a vet?
