I am sick of my life ...?

And I believe it's time for me to write about it. I came to the US when I was young, full of life and very extroverted. I made a few friends, and we did the usual things especially play Sega Genesis. Several years later, during middle school, I begun to skateboard and play strategy games (Starcraft, Warcraft III). During that period I had several friends, but still no luck with girls. I dreamed about having a girlfriend, but I never got one during those years. High school came, my freshman year was great (All A's), and I continued skateboarding and playing chess. Sopre year came, I played on the tennis team, and begun playing World of Warcraft and DDR. My grades were excellent and my parents very happy. Although few things begun to happen . . . I begun developing anxiety, including "Having difficulty swallowing". Junior year begun, I struggled with my acne and anxiety issues. I was close to having zero friends and played World of Warcraft Friday, Saturday, and Sunday. Almost for an entire year I did not step out of my house, except for going to the gym. Anyways, I triumphed junior year with good grades. Senior year came. During that summer I lost my virginity to a prostitute and had a second encounter the next day with another one. I begun cles, had a brand new laptop, and played World of Warcraft until 2 to 3 in the morning every day. My grades began to collapse and I worried I might have HIV. Senior year was finished poorly, but I still graduated with an academic honors diploma. I left my house and left for college. Failed first year of college and moved home. Second year came and I failed my courses again. I was not able to concentrate in my studies anymore, and had to run away by going to the gym. During those two years in college I found several friends that loved to get drunk, and begun to get piercings. I entered my third year of college, with very serious intentions to do well, and struggled very hard with serious OCD, anxiety, and worrying about EVERYTHING. I struggled very hard, but finished with good grades after all. Summer came, I had another encounter with a prostitute for my 21st birthday and this time the condom BROKE. Also, during that summer I drank so much alcohol that night that it took me at least one week to recover ( I also had SEVERAL at least 8-10 alcohol overdoses). I blacked out several times, puked on my body several times waking up the next day to wonder how I got there. Anyways during that summer I worried so much that I got a PCR RNA HIV test and was found to be negative. My fourth year of college came and here I am, I drink little alcohol and gave up my bad friends. Although I am now in a good program at school, I have no friends and continue having OCD and anxiety. It gets to the point where I can't relax anymore, constantly thinking about odd ideas and yzing everything. It's taking over my life, I want to change my life but it's so hard for me! I still do not talk to any girls... I mean am not a bad looking guy, I watch my diet and go to the gym allottttttt. What should I do? I am sick of my life ................... I want to do good this semester but I struggle so hard in concentrating and my mind continues to wander, worrying about every little thing. I even wake up at 4 in the morning before school to do my studies. I feel I am stuck.
