Don't just start taking something, talk to a doctor about what is safe to take. Sometimes it is a matter of weighing the risk of taking it vs. the risk of not taking it, but also some meds are safer than others in pregnancy. You REALLY don't want to cause a problem for the baby. Have you tried exercise? It is said to test better than anti-anxiety meds for reducing symptoms of anxiety and depression.
I stopped taking Zoloft as soon as I found out I was pregnant, well I weaned down off of it so I didn't get sick. I know that the most common anti-depressants used can cause heart and lung defects in babies. Though there are some medications that are lower risk and your OB will know which ones are safest for you to take. I would call either your Dr's office or your OB's office and tell them what is going on. They should be able to get you in contact with the best person to help you. And if you tell them how serious it is they will often expedite the process. Try and be as strong as you can. Take everything one day at a time, if you can make it through today then you can make it through tomorrow. I know from personal experience as well how hard it is to have anxiety and depression. I always just keep telling myself that I will not feel this bad forever and that tomorrow is a different day. Also try to find pleasure in small things, baby updates, going for walks, reading books, a favorite tv show, even things as simple as listening to a song you like. Little good things give you a reason to keep on trying and not get as submerged in how low you feel. Also a wierd thing my Dr used to have me do if I felt a panic attack coming on was to snap a rubber band that I wore on my wrist. You have to snap it hard enough that it stings a little. It would help me because it would give me something different to focus on other than the immense worry that you are going to have a panic attack. Because I used to get so worried about getting a panic attack that I would actually work my self into one. I know you will be able to do the right thing that works best for you and your baby. Good luck!
You need to ask your Dr not us , your Dr is the only one who knows you and can tell you what you should or shouldn't take . A lot of medications have risks . So you need to talk to your Dr about this I'm sorry you feel yucky right now but DON'T risk your baby love .
