I am so confuse of what i want or what's my family wants....?

i have 2 sisters and 2 brothers and they are achievers...i'm the youngest and my parents and relatives are expecting a lot from me to the point that i really don't know what i want in my life. I think sometimes i let them decide or manipulate me. I'm just a very simple and average gal..& i don't have the guts to hurt them
