i have to babysit my brother everyday

im 16 going into college in september. i've been looking after my 5 year old brother for a couple of years now as my dad works everyday and comes home quite late with nobody else to look after him. ive struggled with my gcses because of this as i had to keep an eye on him at all times, with him having frequent tantrums. when i would finish school, i would have to babysit as soon as i get home, so i would stall and stay afterschool to revise, and sometimes just because i dont want to go home. im worried that it will be the same in college and i wont have the time to revise. i asked my dad if he could find a babysitter to look after my brother, and he got quite angry at me and told me i am being lazy and i can just revise and babysit at the same time. he also guilt tripped me by saying that he will quit his job to stay at home and look after my brother so i can revise.
any help please?

I'm not sure if this will help but if you can, tell your school/college that you're a young carer or look into organisations that help young carers. sorry if this isn't much help though

thank you! what do they do?

im not sure if this'll work but look through this maybe if you haven't already https://www.nhs.uk/conditions/social-care-and-support-guide/support-and-benefits-for-carers/being-a-young-carer-your-rights/#:~:text=If%20you're%20a%20young,sister%20who's%20disabled%20or%20ill.

there's a carers direct call line if you're able to call it which is 0300 123 1053 where you can get advice and support with care issues apparently
