How do I give this to God and live?

Right now in my life I struggle each day with sexual issues and eating issues. I'm currently living in a place I thought would be so healthy for me. It turns out that I am being smothered more than I am being helped and financially I'm unable to move out on my own due to family illness. I'm never alone anymore and I live like I am much older than I am. I want to live and be young while I still am, but I'm afraid I just won't fit in. Everyday I fight to not go up to the person I live with and tell the person to screw off I don't have to take care of your family and I won't stop telling me I'm fat and I don't have what it takes to make it in the world. The other night I broke down and found myself in the arms of someone who is no good for me in a relationship other than friends. Well drinking happened and I found myself crying in the persons arms later I was screamed at on the phone to come home now and the person holding me telling me don't let this person control you like this. Of course I went I have too much invested to not go back (emotions and stuff). Turns out my sins I'm struggling with are taring my heart and life apart. Understanding this I'm really ready to change it all. I've been saved for a few years now and served at a Christian Church for a while now, but we all still struggle. Once again I am scared that another church will kick me out instead of embrace with you God's grace and help me, which for the record I do believe the Church I'm attending is really the family and place for the embrace I need. I hate it though part of myself for my behavior and a lot for what I deal with on a daily basis where I live. The person I live with is just giving up and won't get back on the horse to get back to work. I go to work every time wonder why the hell I have to deal with this crap. I miss my family and friends but I won't move back. I'm not sure if I can even find a better job yet to afford living with roommates my own age and not with a family. I need it though I feel like I'm being eaten alive. I want to just beat this persons face in sometimes I know it's horrible to say this but I DO!!! I need help...I desperately need prayer before I knock myself off God's path for me completely. I can't go on like this...and there is only one place for me to go..my parents home and to settle for a life I didn't really want. I know God has planned more for me............PLEASE PRAY FOR ME
I hope all I wrote makes sense.
