Help me I'm drowned

Introduction

It's 1:15 am, and I'm laying on the couch hiding under the blanket, crying my heart out. I'm currently on a trip to London; and let me tell you that this trip has been the most depressing trip I've ever been to. All that's been going on is repeated everyday, I barely have seen any places in London. All I've seen are Hyde park, Westfield, regents park and the zoo. That's it. It's been 3 months of us here and yet I haven't visited any places I wanted to visit. Mainly because of my family, I know this sounds weird. Ever since I've came here it's been hatefully, mainly because back home I'd barely sit with them. I'm always in my room sitting or on my electronics but here there's no place to hide. There are only 3 rooms which one is for my grandma and other is for my father and baby sister and other one is for my brothers. Where do I sleep? I sleep in the living room everyday. On the hard couch where I've been having back pains and neck problems. That's not it. Around 11am I open my eyes to sunlight on my face, windows open, tv on very high volume, my family eating next to my face which makes me feel so uncomfortable and disgusted from the smell. My grandma screaming at me to wake up when I can't sleep until 5 am. It sucks here, I hate everything about this place.
