"Nobody cares."

When I was in first grade, there was a girl who liked to tease me in a rather simple but hurtful way. I was a very talkative child, but every time I said something, she said to me, "Nobody cares." 

Eventually I stopped being talkative and became a quiet child. Now I am a quiet 20 year old struggling to talk to people, with barely any friends.

To top this all, my parents say I'm a very boring person. They don't believe in mental illnesses or disorders that I could have, so they just tell me to get over myself.

I just honestly think that nobody cares.
