I have so much anger and hatred in my heart?

Its getting to the point where I can almost physically feel it. I never been much a peoples person from the beginning but over the past 3 years, friends decided they were too cool for me and now I have just one friend which I'm kinda jealous because he had a girlfriend ,a nice pretty new car which he didn't have to pay for, good grades, good parents and on top of that I get the feeling he pity's me sometimes. I got promoted at my job only to turn out I hate it and Im not respected at all and they work me like a damn mule for 8.20 an hour. took one class of college and failed. decided to build up my bank account but now its getting drained because of my crappy car needing repairs. Never had a girlfriend, parents splitting up. There is nothing good in my life and it getting to the point where I just want to drive off a cliff.
