Congratulations LBL - you have been waiting for this date seemingly for a lifetime.
I hope E's higher power keeps him safe until then and ensures he takes the bed.
Remember to always keep the focus on you, not on him. The goal is for YOU to always have peace and serenity regardless of what E is doing.
Of course there is always the sadness and regret, that is normal and to be expected. But turning E loose seems to be the great task right now.
We have had to turn both the boys loose as well. We miss them at times, but the truth is, life is truly, for us, better without them in it. Terrible to say but the truth is sometimes awful.
I am sorry to hear about your work environment, having dealt with many an unhealthy work environment in my time I know how destructive it can be. If it isn't right, consider leaving. You don't need any more stress.
Big hugs and best wishes.
