I want to run away..but I don't know where..?

I'm 21 and the only thing that I can think of is running away from home. Nobody really listens to me, or bothers about me. I'm also planning to quit studies, cuz im going nowhere in it. I gotta help my family, cuz they're financially broke. The only way is by finding a job, but then my mom doesn't like me go to work. My brother lost his job, my parents aren't working, and one of my brother stuck in other country, cuz he got cheated by his boss, saying that my bro could earn higher. My family gotta settle lotsa debts and I don't know where is this going.. I'm in my semester break, and my new semester is gonna start next week, but my parents are totally broke, they don't have money to give me to go study, and I haven't even bought ticket for my train, cuz I have no money. I am so eager to work, although I'm letting go off my studies, but nobody understands it, and they think I'm wasting money. But I just wanna help.. If I run away, where could I go? Will orphanage accept me? or I would end up being a prostitute, but in this situation, I don't mind doing any job, cuz I just need money desperately. I might be raped, or murdered, or just end up being a beggar at the streets, but I'm just sick of everything, I couldn't stay positive anymore. If you wanna run away, where would you go? any idea? please?
