YouTube channel?

☀️
Hey guys. 
I have been thinking lately, and since I'm going through a tough break up, I thought I would better myself and find myself. I love love love YouTube and I always find myself making videos and editing them, but never actually uploading them because I'm scared what people would think. 
What do you guys think about me starting a YouTube channel? 
Beauty, favourites, storytimes, DIYs, and travel. And probably Vlogs! 
Who would watch it? 
Is there anyone out there with a YouTube channel with any advice for me? 
I really want to follow my dreams and just go for it but I am so nervous!
