sad moments in life captured in the brain coming out again causing melancholy

I was thinking about old friends and acquaintances. I was listening to enya like I sometimes do. I was crying because I don't know anymore about them and I am all alone now. Maybe they are dead now. Maybe some of them are doing the exact same thing that I am doing. probably they are just wageslaves now with families to take care of. here i am still not achieve anything of note and i listen to enya and cry in my bedroom.

I went through something similar recently. You're not alone.
