Pregnant and CONFUSED!!!!

I’m 16 years old and 35 weeks pregnant. I’m still with my boyfriend who I have only just realised is a total jerk and now I can’t get out of this mess I’m in!!! I live in New Zealand but have temperally moved to Australia with him for his job. I don’t think I love him anymore but I can’t go back home because I’m too far pregnant (and I don’t know where home is). My mum lives in Sydney but I haven’t been allowed to live with her since I was 14 and having a baby has just made things a hell of a lot worse for me in that department (as well as every other). I really don’t know what to do with my life. Befor I got pregnant I was living with my nan but I don’t want to go back there with a baby even though she would let me. She would only let me cos shes a loving person. I treat everyone in my life like shit and I don’t know why I do it. I’ve lived with so many different people throughout my life and have wreaked things with them so really, it seems that I don’t have any options but to stay in this unhappy relationship, but I don’t want to bring my baby up around this. I just don’t know what else to do. I don’t want to live in Australia so I can’t go out and get a flat or anything – it would just be a waste of time. Even back in NZ I’m not sure how I’ll survive with this little baby on my own. I can’t cook or anything. I won’t be able to get a good job, I can’t go back to school at the moment…My lifes just so F****D!!! I wish I’d have listened to people that love me years ago so I wouldn’t be in this huge mess I’m in today. I’ll never forgive my mum for what shes done. She had me when she was 16 as well so she knows how it feels and still she won’t open her door to me as a place to live. Please someone help me, tell me what to do. I’m sick of listening to myself I always end up in an even bigger mess then when I started!!! Help me
