Depression and anxiety

12 days post birth of my daughter and I feel like a ticking time bomb... I have a horrible history of depression and anxiety I've been on antidepressants since I was 13 years old... I was stable for 7 years until I got pregnant with my daughter in July via IVF. I took myself off my Wellbutrin but stayed on my Zoloft throughout the pregnancy. 2 days after giving birth my world came crashing down all around me. I had a c-section and high blood pressure ended up having to stay another night in the hospital and they put me on Xanax. Last week I saw my doctor to get back on my Wellbutrin but she started me on 150 (used to be on 300) and also found a new therapists.. I'm suffering so badly I lost 30 pounds in 12 days I can't eat, I can't sleep I feel like a walking zombie. I hate feeling like this and I wish I could make it stop!!!
