You sit at your computer learning stuff using the search engine "Google" wont benefit you in the outside world. Seeing that you failed to search "How to type in proper grammar", I think your teachers can help you out with that. You have the mindset of an elementary school student.
I see what you're going through, every teenager goes through a certain depression disorder and I guess yours is more serious than others. Sitting around your computer wont fix anything. Go back to school if you dropped out, you don't want to be working at McDonalds the rest of your life. Maybe one day i'll pass by and you're giving me a McChicken LOL.
