Martina, I'm so sorry. I lost my job for the same reason. Dragginig yourself to work when you're in the throes of a deep depression is easier said than done.
You said you have great credit. This is a shining light. You can call your creditors and let them know your situation. Many creditors will offer you a hard-ship dispensation where you will not have to make any pymts for 6 months, or will at least lower or cacel interest rates.
As far as feeling that you ruined your family, I felt that at first too. But it was the depression that was running the show, not you.
For now, step back and take a breath. Being fired when you're the breadwinner is so traumatic that we often can't see all our options right away.
I'm here to talk if you need, pm me. You'll be in my thoughts ad prayers.
