I agree that it sounds like you're worried about what the audience is thinking.
With any problem in life, there are two solutions: stop what's causing the problem, or change your perspective so you don't think of it as a problem.
For the first route, I'd suggest trying to commentate. Getting used to a personal interaction with those audience members will reveal their normal reactions to stream. If your stream isn't filled with monsters, then they probably aren't judging you nearly as hard as you can imagine them to. If they are monsters, then don't seek their approval. Awful people's approval means nothing good anyway.
For the second route, I'd suggest treating it like any other match where you don't get nervous. If you normally aren't trying to prove your worth, then don't think that way on stream either. There will always be another match. Anyone who's judging you is a judgmental person and there's nothing actually wrong with you. And so on.
