Bro, I would feel the same exact way... But you know what, just keep your chin up and be the best YouTuber you can be! You'll get your opportunities. So what if your friends got their's before you? A lot of people have been in the same position as you, they just got noticed quicker. Good things come to those who wait. Plus the way I'd see it is they get their's handed to them when you'll actually work for your's, they'll take it for granted while you'll actually be able to soak it in and actually appreciate the opportunities handed to you. Just support them while they get this one and wait for your's.
