I understand how you feel. I also think that some when in my 40-ish years of life I would be reminded about Death Note and Code Geass and all that fangirling time with other fandoms, maybe I'd be like "Lulz those anime I watched.. Those doujinshi I read.." or be miserable again remembering the death of the characters.
Either way, I realise that I could blame most of this to the unstable teenage hormone.
And Sunrise for fucking with my mind and emotions.
