I went through the same thing. I had no appetite and hot flashes as well. I dropped over 28 pounds in 2 weeks. I also felt the "baby blues". After about 2 weeks I asked the doctor to be put on Zoloft. I only took it about 3 months and it helped drastically. I also switched to bottle feeding my baby after about a month. It seems like you may be experiencing the typical "baby blues". It should only last 2 weeks. If you still feel this way after two weeks than you may be experiencing postpartum depression. If its truly postpartum depression, doctors told me it would subside after just a few months. Its up to you wether you would like to ask for some type of medication to help get you through it. Zoloft is very mild and very easy to come off of. But I would give it two weeks and see how you feel.
