I have generalized anxiety disorder and major depression. I'm currently talking to a therapist once a week and it really helps. I haven't taken medication yet but I will soon.
I don't blame you for being anxious about the pregnancy. I would talk to the doctor about taking anti depressants meds that is safe for pregnancy.

click on abc which meds u use and see if it's safe or not. Always contact doc for double check before taking anything during pregnancy.
Congrats again!
