Well, as there are some very serious things going on right now in your life I would suspect that your T would understand and prefer that you contact her, or a crisis line or something, especially as you mention that you are concerned about your children.
Are there any safe supportive family or friends that can help you with your kids right now? Does your T even know about the recent incidents? I know that in my case, I called my T after my H's arrest(different circumstances btw) as I felt it was a crisis and my T agreed with me. He wanted to talk with me and make sure I was handling things alright.
