You didn't have your heartbroken, sorry to say. When you TRULY love someone and they break your heart, you'll know the difference.
When I was 15, I was with someone for almost a year, and she was my first in more ways than one. She dumped me and a week later started going out with my best friend who told me "What was I supposed to wait forever for you to be over her?" I lost someone I truly cared about AND I lost my best friend.
THAT is a case of being 15 and being heartbroken by a true love.
Don't know what to say... You probably have had some sort of social issues for a long time. But you are a great bassist aren't you? I'm pretty sure music healed your wounds. Thanks for sharing your story with us.
