Welcome to Just Answer. Of course, the first thing you will have to do is find a job with a salary sufficient to cover lodging, food, clothes, and transportation. Moving out generally means putting education on hold for a few years since there are few jobs that allow enough time for work and education. Jobs available for those without a university education or some specialized skill are usually low paying with less chance of advancement (and the higher salary it brings). Unless you know someone who can finance all of this for you, it might be better to seek family counseling and try to patch things up with your parents until your education is complete.
Who to call for what? There is no one out there who is going to take care of you. If you are being abused you should contact the police. Otherwise, you need to find a job before you do anything else.
Yes, I understand what you mean. You can discuss this with your local welfare office to see if there is any support available for someone in your position. That should be the first place you go. They may assign a case worker to you to evaluate your situation.
