Is it normal for teens to be bored?

Yeah I'm bored. But I'm seriously wondering. Most of my life I hung out with my friends 24/7 and summer was NEVER boring. Literally I never got bored. I didn't realized how lucky I was to be surrounded by friends I could visit and chill at their house everydayl. I still hang out with friends everyday or every other day, but if I don't hang out with someone for one day and sometimes all day, I become extremely bored. On top of that I play online games, videogames, draw, paint, read, clean, write music, play instruments, and I'm also learning how to use HTML, but I still get bored doing the things I love. Is this normal? And either way how can I get over my boredom. It's definitely not a problem of what to do, I think it's something mental.
