Ideally, I only cam when I am feeling my best. That is when it's the most profitable for me. Viewers watch us because they like the "personal" side of it, but I don't think that means sharing every moment and every side of ME, actually. That's just how I see it though. I want to figure out how to run my business in the most profitable way and I don't think that's it. I also have a personal boundary of not looking to my audience for emotional support. Something else I like to keep separate. I find that otherwise, I open myself up to people blurring the lines more easily in ways that aren't conducive to good longterm provider/client relationships. It seems like I'm inviting unhealthy interactions. But that's just what works best for me, on my cam site, with my persona and target market.
But to answer your question, which wasn't should you, but can you? Yes I imagine you can. And I'm sorry you are dealing with stuff that is making you want to cry! I hope it will get better soon.
