I hope working out of home works out for you, but I think working out of it would be the better option even if it means a bit more effort/lesser pay. The only reason I say that is that I was in a similar situation as you, and when you see the same people 24/7 who drive you crazy, your brain starts to rot. Gradually you forget that a better way of life can exist, and are just stuck in a never ending rut of hatred and disgust.
The key is to get out of the house, even if for a few hours. Who knows, you might meet some cute girl with more facial decoration than yourself. (I meant that in a good way).
The problem you seem to have are a lot of obstacles, and I went through the same thing and it is really really intimidating. When it is so intimidating you just procrastinate, until your brain is dug deeper.
Also it is a pity that there is no bus functioning for you. Some of the cutest girls I've met are courtesy of buses.
As for biking, it isn't a bad idea. Bike to and back from work, even if it is half an hour, you'll enjoy the fresh air and exercise. Who knows, maybe once you start working and saving for a car, you may actually meet someone at work willing to give you a ride regularly.
See if you can get a job at a local mall. People are bound to go to work at a mall from your locality. If you post some ads or whatever you can possibly get a ride to and from, while you have your bike as a backup.
Try to save your money, and forget useless shit like gaming for now. Get a car that is good enough to get you to work and back, and you are set. Working out of home is ideal for many people, but that's also why I've hardly seen it work. It is just too good to be true, most of the time.
The ideal thing would be to save some money and move to the city once a job is guaranteed there. This sort of stuff is just far easier in a city. You might be lonely there, but you have us to keep you company till you make friends.
There's a gas station owned and operated by a family about 5 miles away. The closest thing other than that is like 25-30 miles away.
OK riding a bike to some place 30 miles away isn't possible.
