Is it normal to have a successful life after growing up not so succesfully?

Im only 19 first of all. Im sure to a lot thats young and have time and stuff but still. I know a lot of people my age who are so vibrant, talented, out there, mature, etc, and Im just blah. Throughout the past, Ive never been satisfied with my social life since like 3rd grade then all of a sudden it changed and I became so insecure and paranoid and too aware of my surroundings. Its lead to me to this point, where I can say I really have no friends that I can call friends that I usually go out with you know the main group. I can also say I havent had the best luck with people liking me, for some reason people just dont accept me and ive been living with this since like 6th officially that Im surprised I havent committed suicide or cut myself (dont plan to far away from that but at the same time shocked cause people in my position do). Im in college now my first year and trying to transfer to a university for one of the reasons that i feel itll improve my social life and just self esteen over all. Im also so determined I plan to work in the entertainment industry because Ive always been into it, my life goes by it and as much as I am, i dont compete with the people who actually show it while Im here hidden with so much passion for it and they wouldnt even expect it. So when i pursue it, I plan to shock everyone and turn their heads around but at the same this is what no one knew about me and its not that I changed its that you never really knew me did you? In the house, Im so vibrant, everything everyone else is but outside and for some reason I just get intimidated causing me to look boring like I have no interests at all when I happen to be in love with the same music the person next to me jumping around is too! The best thing is I get accepted to the universities I want and just develop a new lifestlye with a diversity of people cause thats where your person gets to shine not like in hs where who you are is a shame or popoular, nothing in between. I want to change my life but its not really a change, its more of like exposing my true character I am that i only seem to be able to express it in the house not out there in the world.
