I reached a breaking point when my GC sister stole money out of my account and when confronted with it my parents acted as though it was my fault. So, I booked a flight out of their (my old city) and left. I was planning to leave for school a few months later anyways so I just left early. I was working full time and going to school while living at home before NC so I had some money saved up which helped and then I got another job in the new city. It was difficult but work it.
If you are looking for some advice, I need more info to help you. What is your age and do you have the means to leave? If not, make a plan to start gaining independence. You need a place to go, do you have one in mind? Can you start applying for jobs in a different city?
