Parental or Adult Advice Really Really Needed 4 Distraught Girl in College :/...?

I"m on my second yr. of college & I am very extremely depressed. I want to transfer from my University to a bigger University in a city by my Jr. yr. (nxt. yr.) 2 get a new start but there's a prob. I'm from a really small town and went off 2 a nearby Univ. 20 mins from our country home in which I commute. I made tons of friends & really was having the time of my life & at first I loved college & was very in love w/ the college life but then something really bad happened 2 me that's changed everything. I got into a emotionally abusive relationship were I was treated horribly & after the guy left me broken and scarred he transferred w/ a smile on his face & is very pleased 2 the damage he's caused 2 my life. So I really need 2 get away from all the memories and heartache he's placed in my life that still effects me. I cry nearly every night I go 2 bed over everything he dragged me through & sometimes think of commiting suicide but as a Christian I know it's wrong otherwise I would. My friends think I need prof. help & have noticed my aloofness which is not at all like me but I can't help it. Also I can't leave home cause my parents do not want any of their children 2 leave. I have brothers in there 30's who still live at home & have nothing w/ college degrees. When I tell my parents this they say I won't know how 2 drive in a city or it's expensive,dangerous or how will I get my all my stuff 2 a city etc. which always dashes my hopes of getting away out of my sorrow. I work got to school & pay for all my stuff that I want or need. I'm an indpendent person & really want 2 get away... Please help me. Anyone have ne advice or help...I've hit rock bottom & really want to give up.
