I'm sorry to hear about how you felt numb in the past and walked around like a zombie, but, it's great you were able to find something which could help you snap out of that mindset. Also, I listened to leave me a alone, I've never heard of them before.

But, it's such a great feeling when you find an artist that resonates with you, there's a punk band who've I've listened to since I was a teenager and there are songs they have which are almost like they were written about or for me hahaha.
