I really need help on what to do with my life.?

I am nineteen years old. I am a very well presented girl. I am well spoken, i have worked in different government departments through trainieeships. I successfully completed cert II and III in Business. I really would love to get involved with helping people Eg: Phycology, Disability care, Family care something in those areas. I did not complete my VCE and i noticed in alot of the Course Guides that entry requirments for some of these areas VCE is a must. I really am stressed right now of what i need to get completed in order to start studying for something that will be a long term stable career, As oneday i would love to have my own little home with a child that i can support and not struggle. Im really stressed that I will go no where in my life at the moment, It doesnt help that all my friends around me dont care about there lifes only there boyfriends who half of them are braindead and are into drugs.
