Dealing with Depression and Anxiety

Andi
So, I've been diagnosed with Depression and Panic Disorder. I've been treating it since I was 19. I'm currently 26 and pregnant with my second child. The first time I got pregnant, I came off my meds and was fine. I was a very happy pregnant woman. This time, it's the opposite. I came off my medicine and I'm so angry all the time. I'm moody and emotional and I hate it, which makes me more moody and emotional. Is there anything I can do (other than get back on my medicine) to treat the depression and anxiety related issues?
