Just Some Simple Advice To Offer A Poor Girl?

I graduate high school next week and nothing has changed. I still have no one to talk to and no one to hang out with. Every weekend consists of me being in my room on the computer. I don't have any transportation, cuz im such a loser that im almost 18 and cant drive because everyone was scared to teach me. So...this is my typical weekend: sunny hot day (im living in the south) so the conditions outside are UNBEARABLE, my neighborhood is completely deserted, none of the bus routes run in my neighborhood (WTF) and my mom would kill me if i took a taxi because im always broke, and it makes no sense to get a job because im leaving here in 3 weeks to stay with my aunt and not have to live my life anymore. The house i live in has an unmotivational atmosphere, no one does anything but sleep and eat. I don't have anyone to hang out with for some reason. I guess im not a likable person, no matter how i tried to be annoyingly perky or social it just didn't work, i've never been a people person or charismatic so whenever i talked to people it just came off awkward, PLUS I NEVER GET THE **** OUT OF MY HOUSE SO MY PEOPLE SKILLS SUCK ANYWAY!. I am bored out of my mind and i hope that when i get away from here things will be SO much different!!! what am i supposed to do??? Im tired of sitting on the computer every weekend but there is nothing else in my house to do?? did i mention it's blistering hot where i live so unless i want to kill myself theres no way ANYONE is gonna ignore the heat advisory and go outside?
