There will always be people who don't understand it, and thinks it's weird. Many of my friends thinks it's weird that I do YouTube as well, but I don't let that stop me. I love creating videos, and nothing is going to change that. If you love making videos, you should continue to make videos.
As for your parents, show them that people like watching you. You have almost 150 people who are subscribed to your channel. That's a lot, and it's going to grow the more you do it. When I started YouTube, I already moved out of my parents house so they couldn't stop me even if they tried. But even if I did live with my parents when I started, they still would of let me. My parents have always been the kind that lets me do whatever I want, as long as it wasn't something life threatening. My Step Mom was very skeptical about my videos, but now she's accepted them and watches them. You got to prove to them that this is what you want to do. Make them realize that it's your passion.
