Dealing with friends death

This morning my husbands and my best friend shot himself... Im almost 21 weeks. My husband is beside himself and understandably so. I've never seen him cry until now. I am a total mess and watching my husband is making it worse. I've been crying since 8 this morning and now I can't sleep. Should I call my doctor tomorrow and see if there's something I can take or do? I'm so heartbroken and I know this stress isn't good for my unborn baby or my 21 month old. (My sister has my son right now). Just feeling completely lost.
