Scared ftm

I know my hormones are completely everywhere now that my new baby girl is here... But I can't stop freaking out that I will lose her. She has passed all her health tests, but I'm worried when she wont stop crying after eating, changing diaper, burping and cuddling, she gets congested but not in the nose the sound comes from her chest... When she cries like that I break down because I'm so scared of losing her... Any advice or suggestions? She fights burping so bad and sometimes I can't get her to burp until it's almost time to eat again and she gets severe hiccups from it... Am I just being hormonal or is this something I should worry about I go to see her doctor tomorrow but right now I'm still.freaking out...
