Thanks to all the ladies who chimed in with advice.
I just wanted to say for those of you who feel awful emotionally, don't know what to do, think you need help, etc., that it can get better. I am not completely well and still have some hard moments, but I called my doctor to talk about PPD and ended up going on an anti-depressant and a hormone treatment to deal with some of the physical symptoms I have had.
These things haven't been a cure-all, but they have helped me so much. I feel like I can function now. I can have conversations with my husband without bursting into tears in the middle of them. I can hear my baby cry without sobbing about what a terrible mother I am. I can even have sad moments without completely losing it and getting into a depressed funk.
Hope you all are doing well and that if you think you need help you will at least talk to your doctor or another qualified professional.
