Is it normal that i get very nostalgic when i listen to pink floyd?

Okay, my favorite band is Pink Floyd. And I love them to bits, love their music and everything, but when I'm reading or listening to the lyrics, or simply seeing the song titles, I get overhwelmingly nostalgic, which makes me very anxious.
It started with my Syd Barrett obsession, which worsened my depression a lot.
Since then, I can't help but think that he's gone and Rich is gone and they'll all soon be gone and forgotten, and it makes me feel so bad.
I also get pretty anxious. This may have to do with the fact that I 1) have depression 2) have anxiety 3) I daydream so much I can't realize when I'm actually alone.
Is it normal? And how can I stop it?
PS: I'm really young so it's not specific nostalgia, it's just the feeling.
