Any Places That are System Safe?

I would like a place to know people who struggle with issues like I do, and yes, I would like people who have fun in moments, since you can’t be upset ALL the time. I don’t know, I want to engage with systems more, but don’t know where to look. Are there any places I shouldn’t look due to the toxic nature of it?

If all places aren’t great, what’s something that’s less than the rest?
