I am so anxious, the memories of how I used to feel are coming flooding back (crippling anxiety/sickness). I am 5 weeks pg (2nd child) and terrified I am going to cause a miscarriage by feeling like this. I received a letter from a vindictive ex-friend who I have cut out of my life and it has triggered this. Will it all be ok? Please help, crying, please don't let it come back adn please dont let my pregnancy end becasue of me.
