It's OK to talk to people. It isn't stupid or bad. That's what support groups provide... easing loneliness and talking things out. There are other people going through the same things you are who are safer than a random facebook contact. Do you know if there's a separated and divorced women's support group in your area?

Even if you aren't up for support in that area, maybe a grief support group can help. It's OK to just listen to other people and not talk about your own situation until you're ready.

All the best.
