Help me fund my education in the UK in 2025 26

Hello everyone, I'm Marisole and I'm an 18 year old Italian student who has decided to complete her last two years of school in England, specifically at the Itchen sixth form college in Southampton. I made the choice to graduate in England because the subjects I'm completing are very similar to what I would like to study at university. All this motivates me to complete my course of studies in England. But the payment itself for college and the cost of living are very high and would cost a total of £20,000. My family in Italy can help me contribute half of the cost and in the coming months I will try to give my part while working in Italy during the summer to lighten the expense for my parents, unfortunately I don't have the possibility of obtaining a work visa for students because I study at a sixth form college. In any case, receiving a little of your help would be a great fortune for me.
