Heartyace, I have a really long story that you might find interesting. If it's too long, just skip to the bolded part.
ramblerambleramble about irrelevant part of story, because I clearly was not thinking straight.
So how's he fixing his problem? He cut out everyone he possibly could from his life, so he wouldn't have to deal with his old, 'fake' personality. (Really intense, and I personally wouldn't do this, but whatever). Now, his only goal in life is to be happy. He stopped trying to force himself to make friendships. He stopped thinking so negatively about others. He started smiling more, and doing other small things to make his day better. Now it's become a part of his personality. It got to the point where making other people happy made him happy, and now he's finally letting people in. Last I heard of him, he's finally got a small group of friends that care about him, and most importantly, he's happy with himself.
Of course, this is just one man's story.
EDIT: Wow, wtf, did I just type all of that up? I should get better sleep..
