It is difficult sometimes to feel so alone. Believe me, I KNOW! Surely you could find someone to watch D10 so that you could go on your trip. Getting away would probably do you good.
I don't even know if it helps to say this, but you are definitely not alone in your thoughts and feelings. I dare say many of us have gone through similar emotions during our time of divorce and recovery. Sometimes life is just hard and being an adult $uck$!
Take it one day at a time, G, and it will get better. Until then, hang in there and try to focus on the good. You know that old saying "fake it til you make it!"
