I haven't gotten out of my bed in a couple days, any tips to motivate me?

So basically I've had depression and felt pretty lonely the past couple months and it's gotten worse recently because my one and only brother went on vacation with his girlfriend and her body pillow of leafyishere and they won't be back for a while. I won't really have much interaction with anyone since its summer and All I have is overwatch and some Doritos to keep me busy. And I don't know if this makes it worse but my bother got a bag of rats at a flea market in some place in Ohio, we live in PA, and he just kinda left them in his room and they are a ton of food out of the kitchen cupboards. And after they finished the kitchen the last place with food was my room because I was cheesing quick play with bastion and eating Doritos when the rats came in my room and tried to get on my bed where I was laying and I've been fending them off for three days or so. I haven't been able to go to the bathroom and get more food or anything because I'm afraid of getting bitten by these hungry rats. I think they might have rabis or something they won't quit trying to get my food. I might be able to whack them with my minecraft sword in my room and kill them but that's kinda unethical. What should I do?
