I need advice. I'm procrastinating on getting a job that will get me out of my abusive situation.

Partly because my job is not my passion, but will allow me to pursue my passion (art) and give me the financial power and freedom I need to go on my own. But my mind hates it, I hate sitting on the fucking laptop and doing it, because everytime I do it, someone comes in starts abusing me, and making fun of me doing my work, because they know what I'm doing and dont want me to do it.

Its so fucking exhausting, I want to kill everyone and not care what they think, but it's so hard to focus on doing what's right and will get me out of this. I need discipline in my life, I'm passionate and since it's all over the place it develops into overindulgence.
