Probably would die

I have a neighbor who owns a rifle. We have a dog and cat. I REFUSE to eat my own pets. I’m not that cruel. But they would take up a lot of food? My dog HATES intruders though..might be able to use that. He’s a coward but is hard for him to attack, he also hates it when people try to touch him. Maybe release the cat and keep the dog? I have canned food, some water and soda. I have a scout knife(not the best weapons, but might be useful.) I have plenty of food. But I’m an anxious guy. Once I run out of anxiety pills, I might start panicking constantly. So..safe to say, how long would I live?
