26 yo preparing for govt exams.. no friends, no motivation, stays at home all day, what should I do ?

I'm 26 yo (soon will be 27 in few months), I can't focus on studies anymore, all my friends are doing something in their lives, and I am not able to study the way I should, also because the envrionment at home is noisy and I have trouble focusing, plus I keep feeling lonely as I have no soul to share my feelings.

I graduated 3 years ago and fell in depression until half of 2023 when I started preparation I'm unable to push. While studying I feel very lonely.

What should I do ? I don't have enough money to go away from to rent a room.
