Welcome to the group,
I also can relate, I had panic attacks and nightmares about how my family would react to my leaving, but it was still something I HAD to do- telling them in person was the hardest thing I have ever done, but I did survive the ordeal & I know you will too.
Yes there will be depression and confusion and anger (and I've never been pregnant, so your feelings are many more times intense), that is completely normal
Getting some professional help is important if it is available in your area, I am happy you have your husband with you supporting you during this difficult time....
hugs to you both & keep us posted on how you are
