If i dont listen to black metal for a period of time, i will feel insecure?

Hey so, what i learnt, and im totally serious, i wasnt listening to black metal for like 1 week, and im seriously depressed, i couldnt eat, couldnt sleep and my mood was totally off, now i started listening again and i feel so happy and so empowered and so glad i cant even tell you, why is this? Is there a biological reason for it?
