Peace be with you Iqra, and welcome to the forum,
Life is incredibly unfair, and there is often very little you can do about it. Your parents brought you into this world, so they do have a duty towards you. But you also have a duty towards your parents. Apparently, in 2022, the average cost of raising a child in the UK starts from £150,000. This seems very high, but at the age of 74, this puts me off having any more children.;D The first 73 years of life are the hardest, then it gets harder. I say this, not to beat you down, but in order for you to find the spirit that exists within you, to fight one more day, and always one day at a time.
If you are dependant on your family now, wait until you have to go out into the world and earn your own living. Life will either beat you down with all its problems, or you will learn perseverance, resilience and kindness, and you will learn to stand up for yourself. There is often very little you can change in life, other than your attitude towards life.
Pray to Allah for the wisdom, strength, peace and perseverance to do his will. Give thanks for all the things you have. Being thankful for a bed, shower, food and education are things we take for granted, but they come at a price.
May Allah bless you on your journey,
Eric.
