My experience is that the moments of depression can arise from time to time.
That said, I'm glad to hear that you're doing better.
Tips on coming out? That's a tricky thing. I was very clinical and direct when I came out to my family, friends, and coworkers. But, I think the details will vary depending on all parties concerned. Sorry if that's not specific enough, but I've found that I've had to be adaptable in my comings out.
