With the exception of the childhood history, I do relate. I know I'm a beautiful person on the inside if people would just look that far in me. My friends that I have do. I didn't find them until very late in life, like 22. Everyone else I hung out with up to that point were using me. I was fortunate that my father bought me a car, so everyone wanted a ride. My husband, I met him when I was 26. I often think to the movie, Mulan, and what the dad says something to the effect of, "Aren't the flowers pretty? Oh look, there's one that has yet to bloom. I'm sure when it does bloom, it will be the most beautiful of them all." And also when the Emperor says something about a flower blooming in adversity is the most rare and precious of them all.... Anyway, I always found those words semi comforting after the movie came out, but I am a chic.
I always told myself growing up that I wasn't going to let those people affect who I am, and I was never ever going to turn into one of them. I just work hard at doing the right thing and to hell with everyone else. I realized later in life that there were guys in high school who had a crush on me. There were girls who wished they could hang out with me and thought I was too cool for them (even though I was a friendless nerd). There were also people trying to be my friend and I didn't notice because I assumed they would never do that. People do look up to me and like my charity and kind heart even though they never showed it.
The military taught me that my mind and body was capable of a lot more than what I ever imagined, and all you can do to tap into that is constantly challenge yourself.
My greatest suggestion to you is to find some inspiration. You could look up Catholic Saints, find a few that you relate to, and read up on their lives. In addition, read biographies of people who you always admired or wish you could be more like. Many of your billionaires are self made. Oh, and the teen version of highly successful people is a good read too. I personally found The Tao of Pooh an awesome book for me to find my peace and center type thing.
Since I looked at your interest and saw music... I also totally recommend Beethoven as a Biography and Discography (especially his 9th Symphony...the scherzo and trio/2nd movement) and the Immortal Beloved movie. Also, there's a biography on metal, and I found that kinda inspiring to see these metal guys from the 80's going through stuff like that but never losing their confidence. I found the DVD, you are lucky. It's called Metal, A headbanger's journey, and the case gives the website, www.metalhistory.com as well as sevillepictures.com and warnervideo.com. I'm sure Steve Vai has an interesting biography somewhere worth reading. Growing up, I related most to rap music. It did give me a false sense of confidence as many rap artists have to have that section in the song that I call the "I'm the bomb, you aint got sht on me" section. My favorites now (some from then) are Nas, Kanye West, TuPac, Ice Cube and killarmy when it comes to the lyrics. I like Dre and Snoop, but I didn't really like what all they had to say. I think they are more interesting as a biographical type thing. I love Lil John, but that's because he's got some good beats. Oh, and Fort Minor is awesome, lyrics and different beats. But definitely, Nas and Kanye and Tupac has the best to offer when it comes to what they say.
I don't understand how you are 16 and dropped out of college...did I miss something in the OP? Either way, muggers do look for opportunity, but I try very hard to portray myself as confident, and that's not what they look for. They don't care about your psychological profile at all. All they look for is opportunity. Your best bet to avoid it is keep your valuables hidden and don't flaunt it, even the cash. Don't walk around by yourself especially at night. And, always watch your drink in public settings, especially if alcohol is around or you are in a place that's pretty dangerous. Oh, and lock up every time. Car, house, etc., lock it up. Even then, you can still get mugged. My cousin who is cocky, overly confident, and street smart with a history of collecting for guys you wouldn't want to cross even got mugged by a perfect stranger randomnly mugging people by knife point once. I've been mugged a couple times, but I was too drunk to notice, so that's why I don't get drunk anymore. There was one time when I left my wallet on the pay phone at college, but I guess I just didn't get a nice person who felt like they should try to return it (or I got an idiot that worked at the place that was too lazy or didn't know where to look for it when I asked if one was turned in). Either way, I'm just trying to tell you that muggings are randomn and criminals tend to be opportunity seekers, so it has nothing really to do with you as to the why, so don't be too hard on yourself.
I will also say that people tend to like happy people with positive attitudes irregardless of anything else about them.
