Tricia,
Welcome! I'm so glad you found us, but I'm sorry that you need us. I wish you didn't have to cope with the anxiety and depression during pregnancy.
Is there anyone who you trust that can support you in real life? We are here for sure, but in person help is so wonderful when we can get it. Have you spoken with your doctor about treatment? What treatment has been used in the past? Have you a trustworthy therapist? Are you able to tolerate any vitamins with your HG? Sometimes increasing B12, omega fatty acids, magnesium, and calcium have helped folks.
In my pregnancy with Jack, I couldn't tolerate any vitamins but B6 until third trimester. The depression really kicked in at 12 weeks, and I began Prozac at 15 weeks. This is the first time I was treated during pregnancy, and what a relief. There is a risk of withdrawal for baby with Prozac, but given my options, I decided not to wean at 36 weeks. Prozac, Zoloft, and several other SSRI's have not shown to be a risk for damage to a baby in utero.
www.motherisk.org has research to review. If you decide to take meds, it's important you are comfortable and knowledgable about the risks and benefits, so reading up on the research is a good idea.
Look forward to getting to know you.
Suzanne
