Postpartum depression/anxiety & panic attacks

After having my son my anxiety became out of control. I always have panic attacks, feeling like I can't breathe, a lumpy feeling in my throat, chest pain. About 3 weeks ago I started getting cramps in my legs & arms. Followed with a tingling sensation. I've been to the emergency room & doctor & they did a chest X-ray, ekg, & blood work. Found nothing. My doctor seems to think the pain & such is related to my horrible anxiety & panic attacks. Anyone else have depression/anxiety & physically hurt?
