It's good that you know you need help and you are trying to do what is best for your baby. Trauma therapy will help in the long run, but it often gets worse before it gets better. I'm surprised your T is having you go through it while your pregnant. If you think you can't make it on your own you really should go to the ER and tell them how you're feeling. If might be helpful if you printed what you wrote on here, sometimes it's hard to explain things in person, especially when you don't think they will believe you.

Hang in there.

p.s. I"m glad you realize that you arn't able to handle things right now and are considering adoption. That is a very brave and resposible thing.
