Hi. You sound a lot like me. I have those thoughts too about driving off a cliff or bridge. It's ok to have the thoughts but don't dwell on them. One thought leads to another and before you know it your overwhelmed with anxiety and fear. I have been journaling my thoughts now for about a month. It was suggested to me and is has really worked. It actually takes the situation that is so bad and puts it in perspective. Sometimes once you write it down, it doesn't have much power as you thought it did.
