Hopefully things will get better for you, but if you have such a negative stance and only feel sorry for yourself then that is your own fault. You don't have to let time pass by, you can educate yourself about things that interest you over the internet you can really learn a lot of things - from your room. If you feel lonely you can chat with people or discuss with them over forums. (I know it's not like physical communication, but at least it counts for something doesn't it?)
To conclude you should take the best of any given situation no matter how hard it might be for you and how hopeless it might seem, a bit of optimism and you'll be back on your track.
