Feeling too depressed and getting way more demotivated to study

So just 98 days for NEET, already pressure is high in everyone's mind, ik i'm not the only one..but i'm just getting way more depressed. Whenever I sit with my parents, some things happen and my parents fight. My dad has a very bad temper, so he would start shouting at me for no reason (eg when I didnt know how to create APAAR ID initially). He even shouted at my mom today just cuz she doesnt understand how counselling works and asked him about it (she asked him very calmly). Even if he sees my crossing smthg out in my notebook, he'll start shouting at me that I shouldnt be doing mistakes and I wont get good college and blah blah.

I'm even moving to a different place now, due to papa's job change. I've lived in the current city from the time I was 11 until now(almost 18). This adds up to my stress that I will be leaving my school friends here and I wont get to meet them again (they have already taken admission in the current city, and I'm a dropper). I wont even get to see the cats in my society or anything. I'm also afraid it will affect my studies badly since we are shifting to a new place, and we might take 1-2 weeks to settle down.

Apart from that, my parents dont even allow me to talk to my friends much. They say it'll affect my studies. I already spend almost a whole day sitting in one corner of my room with books, but I also want to have fun. I am just wayy too tired of studying😭😭

What's worse? My sister is always snitching on me. If I would text a guy frequently, she will tell my mom that things are going on between us. If I would write something down somewhere, she'll again touch my books and tell my parents. During my boards, she will not even let me listen to songs, telling me why do I need it..Now, she tells me why DO I LISTEN TO LOVE SONGS, LIKE HOW THE FUCK DOES IT AFFECT HER LIFE?! If I would smile over anything, like a meme or a friend's text, she will still snitch over it. And she is not a child anymore, she is already a teenager. I'm not involved in love or anything, but at least give me some privacy!! If I tell her anything, she would just start beating me and slapping me. Even complaining to my mom doesnt work. Even my cousin brother (my age and preparing for NEET as well) says she is a VERY BIG SNITCHER and is even scared to tell about normal school life in front of her.

I JUST WANT TO BE ALONE AT THIS POINT! I'M WAY TOO TIRED OF LIFE😭😭😭
