While I can appreciate why you'd create your own event and won't argue against that, I still would encourage you to consider the need for diversity in such an event. I feel that it's important that we come at this from a lot of different angles in support of integration and inclusivity… from all walks of life. That's not always practical or possible, but it is something worth pursuing.

If you've not heard of it, it'd be great if you could pitch in with BarCampAtlanta. As a community-organized event, this might be just the kind of opportunity you're seeking!

Re: depression: things are difficult because folks have internalized externally-generated homophobia inflicted upon them from others. We've learned to hate ourselves as much as homophobes hate us, and thus have to overcome that first before we can learn how to love each other.
