Post Exam depression

I just finished the may/june series last week and i have been home ever since. Ever since that i have been quite depressed and i dont know what to do.

My friends are busy with uni and work(i had to retake my exams) and so we aren’t hanging out and barely talking. I tried to restart my hobbies but it doesn’t feel the same.

Pls lemme know if it’s not only for me and any advice to overcome this.
