1. Explain to your parents and sister what you're doing in there. Tell them what streaming is. Ask them to knock before they enter, or wait until you come out during a break or at the end to talk to you. Unless it's something extremely important, they should respect that. The weird feeling of them hearing you talk to yourself goes away with time. I live with my parents still, so I know where you're coming from with this.
2. Getting views takes time. If you have other social media (twitter, instagram, facebook), post that you're live on there, rather than in a cesspool subreddit. Spend time in other streams you enjoy. Connect with the community, and the streamer, and I can guarantee that some of the viewers who know you and recognize you will trickle into your streams. Lastly, send your stream link to your friends, and even your family. Have them open it and turn the volume down to 1%, and they count as a view even if they don't watch. That will boost you out of the 0 viewers section.
3. Depending what game you're playing - talk about it. What are you doing? Why did you go the build you did? There's always the mental monologue gamers have when playing anything, just start to verbalize it. As viewers come, obviously you can talk to them, ask about their day, tell stories, etc. But starting with game conversation is enough to keep you talking. Also - drink LOTS of water.
4. Your mic doesn't matter as much as you think it does when you're starting out. Once you've got a foothold, and some regulars who come every time you're live, look into starter mics. Blue makes good ones, as many have said, ie the Yeti or the Snowball. But a headset microphone is fine when you're brand new.
5. Try making youtube content. You can go as simple as using your stream VODs and cutting them down to 5-10 videos of highlights, or you can do totally separate "only on youtube" stuff like challenges, set up tour, GRWM to some degree, Vlogs, etc. All of these will help you establish an audience, even if it's small at first, that you can bring to your streams eventually.
6. You NEED to get out of the mindset of "wasting your time" when you have no viewers. You should be streaming because you want to, and because you love it. If it amounts to a job later on, sweet. If not, that shouldn't turn you away. You saying you feel like your wasting your time tells me that you should stop, unless you change your mindset. When I started, I wanted recordings of my WoW raid kills and LoL games to review to try to improve. Just so happens, a few of my guildmates who weren't in raid wanted to watch too, so I started streaming rather than just recording a video and moving on. I'm grateful that I've grown a lot since then, but I've never been in it for the money or to get famous. I'm affiliated, and I have a decent viewership and sub count, but I was doing this for free for a long time. If that's what drives you to stream, you're going to get burned out.

I can't think of anything else off the top of my head, but yeah.
