yes it's metal and the whole band has extensive lore with masked members and stuff you can listen to 'from the pinnacle to the pit' to hear their general sound
im so sorry you're going through this. maybe you'll feel a lil better after you give an exam though? Perhaps then your brain will see that its not as scary as your brain made it out to be?
I'm hoping you get to have some relaxation soon! Sending you some virtual hugs again, they didn't help the last time but perhaps second time's the charm? <3
