i dont have hope anymore.

i wish i could be happier for christmas. As stupid as this may sound, my cat is an outdoor cat and i let him out a day ago and he hasnt come back for food or anything. He usually comes home at night or when its pouring and theres been no sign of him. I dont want to lose him but im losing hope. Its almost been 3 days and he was my everhthing. He treated me with such kindness when i needed it and he felt like my son. I was so close to him.
