PP Anxiety - how to cope?

Br

I've been experiencing horrible anxiety for the last 5 days or so. My little is 8 days old. My chest is so heavy, I can't stop focusing on my breathing, my head feels cloudy, and my hands and feet are so clammy. I've had crying episodes. He doesn't want to eat much and his diapers aren't what I want and I'm just so worried all the time. My doctor called me in Zoloft, but then scared me with the suicidal and homicidal talk. And besides, by the time it kicks in, I won't have insurance any more to help cover the cost of the zoloft. I'm at such a loss and don't want to feel this way any more. Please help!
