Sleep Anxiety

My baby sleeps, but I don't... Why? Because instead, I spend all night worrying about his sleep, my sleep, his life, my life - anything my unending train of thoughts can get a hold of. I need it to stop but I don't know how. I have never been an anxious person but everything is different now. So what can I do to finally get a good night's rest? See omnystudio.com/listener for privacy information.
