I'm thinking of quitting the job my parents got me and moving out of their house
That's sounds like a big decision. Why do you want to move away from your parents?
Things at my parents house are getting too much for me, I don't feel safe anymore.
I'm sure if you explain your feelings to your parents they will understand and be supportive. Kids shouldn't live with their parents forever, and you have the right to live where and how you want. Especially if you don't feel safe, you should do what you can to make yourself feel comfortable.
I don't want to discuss anything with my parents.
I can understand that. Can you tell me how old you are? If you are younger than 18 then I wouldn't suggest moving until you are.
