Some backstory: 

I'm not very old. I'm 19 this year. When I was 15 my dad walked out on my family, leaving me, my 13 year old brother and 9 year old sister with my mom. My mom was devastated. She didn't get out of bed until it was dinner, and then she'd go right back. It seemed like there was no adult in the house, so I stepped up to be a man. I mowed the lawn, cooked dinner, cleaned the house, and did odd jobs for our neighbors to help bring in some money for my family. I was sad but I felt I needed to be strong. I didn't even cry when I was alone. I buried my feelings deep deep down. 

Those all came back up last night when I went to see my local university's production of "American Idiot," a musical telling a story through Green Day songs. About halfway through a song that my dad used to sing me to sleep with came on. I tried my hardest not to cry, but I soon found tears running down my face. Then silently sobbing, then full on bawling. 
Needless to say, I was super embarrassed.
<bot>: Went to see the Green Day Musical, ended up crying uncontrollably because my dad sang me Green Day songs as lullabies.
