Loneliness and self doubt is one of the sharpest double edged blades. It's a fuel that can fire up so many other passions that can lead you to so many places and to do so many things, but it will also grapple you into the deepest pits of "Oh dear lord no".
You should focus on trying using those emotions, trying to portray it in your writing as vividly as possible. Don't just write it up once on a piece of paper and be done, go over, and over and over. Sit it down and go back to it a few days over. As a reader, I want to be able to feel how you feel, I want to be able to know how you see it. And don't let just one emotion come through, because I know full well that that sombre mood isn't the only emotion that is provoke from isolation. It stirs up anger, internal animosity, jealousy, envy, even people who show no traits of bitterness feel it deep within them when others back them into a corner. Let the emotions flow, get a thesaurus. Learn the words, they are your ammunition, to let everything inside escape into gorgeous artworks that other people can admire. You're writing. You're already a writer. You can literally transform the things in your life that you despise into raw and evoking works that other people thrive on and crave.
On a side note, I know it sounds impossible, but don't let your life tear you apart. Popularity means less and less as life goes on, eventually the traits and characteristics that make you who you are, the ones that people put you down for, are the ones that they will eventually be jealous of.
