Unfair

My life as a child was terrible. When I was born, my father lost his job and our family's financials were very bad. I didn't get to buy new toys, new clothes. Everything was from my sister. Yes, I know that there are more unfortunate people out there. I'm just stating a comparison between me and my sisters. When my first 3 sisters were young, my father was incredibly loaded. Money wasn't a problem at all. Everything they wanted, was just at their fingertips. They would go on holidays together. Buy new toys and expensive clothes and eat pricey places. But that never happened for me. I grew up wearing my sister's old clothes, playing her old toys. It was... Heartbreaking. When I start to understand what it really feels like to have money, to be able to buy things for yourself, I was so into it. I wasn't into damn expensive goods, but I want many things. And i didn't ask money from my parents because I know they're living a hard life. So is it wrong for me to work to earn MY money, to buy MY own things?? If I couldn't feel blessed when I was young, couldn't I feel the slightest luckiness of having and buying my own things?? Why can't people understand me and be fair?? my sisters don't want me to get freedom, when they had the freedom way back. Why can't they give me a chance...?
