I live because of the little bits and pieces of happiness I scrape together from the people around me, the little tinge of satisfaction when I write/draw something and realise I'm getting better everyday, the feeling of elation I get when I do something that I thought I could never do - no matter however small it might be, like walking down that dark lane that always scares me out of my wits all alone, the bliss I feel when I look at the moon and the earth, the reason I delve into books, music, anime, mangas, movies to experience another way of life, the way a smile spreads itself across my face when I break myself away from my surroundings and suddenly discover that I am alive, I am here.
I think you should concentrate on what you have and what you could have instead of regretting what you lost. No home? Alright, try your best to get a job and move into a dorm or something, save up and get one! No lover? Utilise the free time you have by concentrating on yourself and your job! You don't live for a job, a house, or even your boyfriend. You live for yourself, and you live for living.
