The only way to get going is to actually get going. That's a tough thing to start, yes, but at the same time you have to start somewhere. Send out messages that you're streaming, post here, etc. You'll eventually get to a comfortable spot. A youtuber named MorninAfterKill talked about that. He said in one year he only went up to like 300 subs, but the next year he jumped to 22k and then up to over 100k. You just gotta stay consistent with it. Good luck.
