Questions: Family & Friends

AITA, I'm almost 14 and my parents won't buy me anything, like even this keyboard is decayed I'm having a hard time writing this shit. I don't have clothes, like even generic, DON'T SAY THEY CAN'T AFFORD IT, my sisters have all kinds of clothes n shit, and they always say I'm a uselss brat, a moron. They don't buy me food, I always eat their leftovers if there's any, I'm kinda techy but it's hard to compile stuff on 6th gen I3 with that iGPU, while my sisters keep getting new phones n shit, new clothes I just have to sit there and cry like a 5yo or smth, I can't do a thing about it. I'm looking for an advice, I can't get a job soooo I don't know what to do, thankfully my school takes care of the books and school supplies so no worries.

If you are currently a parent or suppose you decide to have children in future, what kind of parent would you be?
Will you be the strict disciplinary type parent or the lenient friend kind of a parent?
To be honest I want to be the strict one but I am 100 percent sure I can't pull it off.
Don't get me wrong I will make some rules which they would have to follow but I don't think I would be able to yell at them, I will most likely try to make them understand the right and wrong. I mean it has worked out for me till now when I was the school headboy Or when I used to be an English teacher.
What about you guys and do tell your reason for your choice.
