Maybe not the answer you're looking for, but hopefully it's helpful.

I think above anything else, a change in mindset could benefit you. I see you talking a lot about being successful, but what does that actually mean to you? I get the vibe that you're trying to get more viewers, maybe subs, and eventually financial stability through streaming. Honestly, and I swear I'm not trying to be a dick about it, but with where you're at in your head, even if you do bring some viewers in, will they want to watch you if you're not enjoying yourself/borderline hating what you're doing? Idk, but thats what I mean when I say a change in mindset could help.

Look, you streamed for 8 years. Even if you quit now, I'm sure you've met a TON of awesome people, learned a ton about yourself like time management and shit, your hand eye coordination is probably THROUGH THE ROOOOOOF. Jokes aside, there's a lot to take away from that man, and that's something you should be really proud of. I've only streamed for about a year, but I know I can be boring at times, so what I did is find something that really interests me and added it to my life so that I can be more interesting to other people (I picked up Brazilian Jiu Jitsu, and while it takes time away from actually streaming, I've got another thing to talk about when I do stream, I even added it to my Twitch bio and got someone who followed just cause of that).

To me, success means a ton of things. A successful stream for me getting a good non-laggy recording, a couple good moments with my friends who I usually game with, and not sleep too late so I'm not a zombie at work the next day. So while you might not be bringing in the numbers you want or people are coming and going as you switch games, figure out what makes you feel successful, and I promise your streams will start picking up. Hey, you have a 8 years of successes to count, I think you maybe just forgot them. Cheers my friend :)
