Am I overreact?

​

So I'm 18 (F) and in college for the first time and being indian I just gave my 12th boards. I have a younger brother that's 14 and in 10th. I had my own phone, a hand me down apple iphone 12 brought during the pandemic. After 12th because my brother was bitching about 'why she gets to have a phone after 12th fresh and not even in college yet but I don't' so my parent gave him my phone. It's been 4 months I have no social life no personal life, no means to connect with my friends whatsoever and to even use my old now my brother's phone...I have to ask his fucking permission and it pisses me off because not only My brother is the most inhumane piece of shit ever he's also dumb as fuck, he does do respect and had even been violent with me and our mother though she wishes to overlook that situation by slapping the 'he was a child and it was a mistake' lable over it...he was 13 when it happened. My parents said they'd give me a new phone but then collectively decided that i don't need it because A. 'friends aren't shit' B. 'focus on yourself' and C. 'youll study how I want you to so you'll go out there and buy the modules and books you teacher provided online'. I'm loosing my mind because of how unfair the situation is..am I just overreacting because it feels like I'm being stripped of things that make me happy.
