Shedding Problems?

[Emily-Fisher]

Okay, so after three months without my cornsnake shedding, his eyes have finally clouded over, his black markings have a blue-ish hue, the black markings on his belly are turning grey and he was showing every sign of shedding. Then, two days later, all signs of shedding has dissapeared but he still hasn't shed. What happened? How can I help him shed? For the past month, you could see bits of skin coming off and such and the scales look loose so how can I help him take the skin off? Do you think that something might be wrong with him? He is three feet long and eats one hopper a week. I am very concerned..
