Has anyone been sick/achy/feeling unwell or just not the same since they had their baby?

My daughter turned a year old this month. The pregnancy was terrible, but all went well during labor/delivery. Since I had her I have felt like a totally different person and my doctor diagnosed me with fibromyalgia. I don't know if this is right, though. I never have energy - not just from being a mother, it's worse than that. I feel like I'm drugged sometimes. My body always aches, I feel nauseous half of the time and throw up a lot or feel like throwing up, inside I just feel unwell - similar to having the flu, I've had two functioning ovarian cysts burst (my doc told me this is normal but I'm having the symptoms again within the last 2 weeks). Early in the morning this lower abdominal ache wakes me up. It isn't sharp pain - it's more similar to menstrual cramps but a little different. When I wake up in the morning I feel HORRIBLE. It takes me about an hour to shake off the incredibly sick feeling all over my body. It really is like having the flu all the time - with more symptoms. I am on Protonix (for a suspected ulcer after the gall bladder test was normal) and my stomach aches are ok while taking it but when I stop it is immediate pain. I was not this person before I had her. I had my thyroid tested and it was normal. I had an ultrasound when the first cyst ruptured and all they saw was a little free fluid in my abdomen from the cyst, nothing abnormal. I get sick a lot as if my immune system is very weak. I am wondering if anyone has had a feeling of illness or achiness or exhaustion that they feel started after they gave birth or during pregnancy. I think that I was severely malnourished during the pregnancy because I threw up every day repeatedly and could barely drink water. I took two different meds to keep me from throwing up but they didn't work at all. My body felt like I was hit by a truck when I was preggo with her. I just feel like I am totally different and that life is miserable and that I am always ill and depleted of energy. Help!
