That emotional rollercoaster you are describing is training your brain to be emotionally unstable.
The dead brain cells are not the most significant threat. It is the threat to emotional stability which is the significant risk.
Wow, now I am aware, does it mean that alcoholics are prone to having bipolar disorder?
Ditto weed and all drugs (toxins with neurological effects on the dopamine, serotonin, etc receptors).
I checked those out on google - wikipedia, and it says it has something to do with the brain...
P.S. besides as a male you need to be working on your masculinity not on satiating and becoming a slave to your emotions. This is the battle for maturity that you face, and unfortunately Millennials are being bombarded with feminism.
No doubt about that... Millennials are very much of a emotional people... Anyway, maybe that's the reason why those emo genre of music came in made by this new generations...
