I spoke with her today and it turns out that i was upset for nothing. They have not told hardly anyone because they are afraid of her losing the baby, so they are not telling anyone until the birth. i have not been excluded at all, we are still friends, she does not hate me, etc. etc.
I am having all kinds of problems now because my antidepressant stopped working and I am not perceiving reality like I should.

I sincerely appreciate all your thoughtful responses!
