why study start feeling isolating or I do not how to explain what i am feeling

I have always study in my specific room since 9 th grade it been 4 years studying in same room I never used to feel negative emotions while studying in that room and earlier even I used to study alone I never felt isolated

But these year especially in evening I feel a weird vibes and see the walls of my room and it feels suffocating somehow it feels isolating or I do not know how to explain that feeling at that moment i just do not want to study at all

Anywhere in my home I started feeling these especially in evening why all these feelings ? What are even the feelings ? Why I never used to feel earlier ?
I wanna keep studying as exams are there but I do not seems to u know even in my room if i watch series or something I feel heavy ,there is no library around my house nor did I have friends who are close or want to study with me for long hours

Is this because I do not have close human connection but I crave for it or what is even this
